Shell model on grids

The method I developed during my Ph.D. workuses mathematical theorems from complexity the-ory to design efficient many-dimensional grids forthe electronic structure problem. Using the formal-ism introduced in my Ph.D. thesis, I will gener-alise the grid-based formalism to provide accuratewave functions for the purposes of nuclear physics,that is solving the Schrodinger equation for nucleiwith realistic interactions. One of the central top-ics of research interest to Prof. Takaharu Otsuka’sgroup is performing efficient nuclear shell calcula-tions. They have developed the Monte-Carlo ShellModel method for solving this problem. Monte-Carlo is a successful method, but does not necessar-ily take advantage of the inherent smoothness of theproblem. The convergence for Monte-Carlo meth-ods is n−1/2 for n points. If one has a D-dimensional

function that is simultaneously m-times times dif-ferentiable with respect to every variable, then theconvergence for the grid algorithm in my thesis, theSmolyak algorithm, is n−m/D(log n)m(D−1)/(D+1).Mathematicians have proved that this is the mostefficient possible method up to a logarithmic factor.

Since I have come to Japan, and continuing intothe next year I anticipate formulating general ap-proaches for solving the Schrodinger equation fornuclei with realistic interactions on grids. Specif-ically, I want to explore how these methods andexploit the advantages of using efficient grids likethe ones I developed in my Ph.D. research.

theoretically. The excitation energies of the 2+1 and2+2 states and the B(E2; 2+1 → 0+g.s.) for 10Be inthe MCSM show good agreement with experimentaldata. The effect of the Lawson method, which wasapplied to remove the contamination of the spuriouscenter-of-mass motion, was discussed quantitativelyand shown in Fig. 1.1. The deformation propertiesof the 2+1 , 2+2 states for 10Be and the 2+1 state for12Be were studied in terms of quadrupole moments,E2 transitions and the occupations of single-particleorbits. The feature of triaxial deformation of 10Becan be seen in the B(E2) transition probabilities.[62, 17, 77]

Heavy Quark Potential from the thermal Wil-

son Loop in Lattice QCD

In this final year of the doctoral course we haveimproved and generalized our previous results onhow to non-perturbatively derive a spin-independentcomplex potential for the two-body system consist-ing of a heavy quark and anti-quark at any temper-ature. This non-relativistic description based onthe spectral functions of the thermal Wilson loopis obtained as an expansion solely in orders of theinverse rest mass of the heavy quarks.

We manage to go beyond perturbation theory andshed the dependence on scale hierarchies by com-bining the non-relativistic Schroedinger picture interms of Feynman path integrals with a space-timeregularized implementation of the strong interac-tions, i.e. lattice QCD. Utilizing the non pertur-bative results for the medium surrounding the QQobtained by finite temperature Monte-Carlo simu-lations, we are able to extract the spectral functionusing the Maximum Entropy Method and conse-quently the potential at any temperature, especiallyin the phenomenologically important region aroundthe deconfining phase transition.

A numerical evaluation of this potential in quenchedlattice QCD (T = 0.78, 1.17, 2.33TC) suggests that

instead of Debye screening, the growth of the imag-inary part leads to a melting of bound states attemperatures above the deconfinement transition.

Experimental verification of self-thermophoresis

Self-propulsion is the motion of an object in aparticular direction by consuming energy withoutexternal forces. It is a typical example of nonequi-librium systems, which have recently been develop-ing but are still not well understood as equilibriumsystems. Recent studies suggest that once the en-ergy consumption of an object can be used to createits local gradient, a new kind of self-propulsion, socalled self-phoretic motion, can be realized. How-ever, the relation between phoretic motion and self-phoretic motion is not clear due to lack of experi-mental verifications.

Our work for answering these questions is to cre-ate a Janus particles comprised of half-coated bygold as an energy consumer to create a local tem-perature gradient. We experimentally showed that

the Janus particle is able to move under isotropiclaser illumination. The particle has an intrinsic di-rection, namely polarity, and accordingly createsa local temperature gradient. The mechanism issimilar to thermophoresis but the temperature gra-dient is not externally applied. Such so-called self-thermophoretic motion has only been predicted the-oretically, while there are no experimental evidences.My results provide supporting evidence for motionscaused by self-phoretic mechanism, indeed sharingthe same properties with its corresponding phoreticmotion. Such an experimental verification betweenphoretic motion and self-phoretic motion is lackingin the present studies of self-phoretic motions [4,19, 75].

In the nuclear theory group, a wide variety of subjects are studied. The subjects are divided into threemajor categories: Nuclear Structure Physics, Quantum Hadron Physics and High Energy Hadron Physics.

Nuclear Structure Physics

In the Nuclear Structure group (T. Otsuka and N. Shimizu), quantum many-body problems for atomicnuclei, issues on nuclear forces and their combinations are studied theoretically from many angles. Thesubjects studied include (i) structure of unstable exotic nuclei, (ii) shell model calculations including MonteCarlo Shell Model, (iii) collective properties and IBM, (iv) reactions between heavy nuclei, (v) other topicssuch as Bose-Einstein condensation, quantum chaos, etc.

The structure of unstable nuclei is the major focus of our interests, with current intense interest on novelrelations between the evolution of nuclear shell structure and characteristic features of nuclear forces, forexample, tensor force, three-body force, etc. Phenomena due to this evolution includes the disappearance ofconventional magic numbers and appearance of new ones. We have published pioneering papers on the shellevoltion in recent years. The tensor force effect has been clarified in [1], while striking effect of three-bodyforce has been shown in [2] for the first time. The structure of such unstable nuclei have been calculatedby Monte Carlo Shell Model and conventional shell model with further developments, for example, a newextrapolation method [3]. Their applications have been made in collaborations with experimentalists ininternationally distributed, e.g., [4, 5].

The mean-field based formulation of the Interacting Boson Model is a new original approach beingdeveloped [6]. This approach is so general and powerful that its applications are being spread very fast inbig collaborations [7].

We are studying on time-dependent phenomena like fusion and multi-nucleon transfer reactions in heavy-ion collisions. A new insight on the role of fast charge equilibration at the initial stage of the reaction hasbeen presented [8].

Quantum Hadron Physics

In Quantum Hadron Physics group (T. Hatsuda and S. Sasaki), many-body problems of quarks and gluonsare studied theoretically on the basis of the quantum chromodynamics (QCD). Main research interestsare the quark-gluon structure of hadrons, lattice gauge theories and simulations, matter under extremeconditions, quark-gluon plasma in relativistic heavy-ion collisions, high density matter, neutron stars andquark stars, chiral symmetry in nuclei, color superconductivity, and many-body problem in cold atoms andin graphene. Highlights in research activities of this year are listed below:1. Lattice QCD studies on hadron interaction [9]2. Lattice QCD studies on baryon-baryon potential [10]3. Random matrix theory for high density matter [11]4. Boson-fermion mixture in ultracold atoms [12]5. Gap formation in monolayler graphene [13]6. Resummation of perturbation theory [14]

1. THEORETICAL NUCLEAR PHYSICS GROUP

High Energy Hadron Physics

In High Energy Hadron Physics group (T. Hirano), the physics of the quark-gluon plasma and dynamics ofrelativistic heavy ion collisions are studied theoretically based on relativistic hydrodynamics and relativistickinetic theories. Main subjects include (1) hydrodynamic description of the space-time evolution of thequark-gluon plasma in relativistic heavy ion collisions [15, 16, 18], (2) transport description of hadronsand their dissipation (3) analyses of the quark-gluon plasma through hard probes such as jets and heavyquarks/quarkonia , (4) color glass condensate for high energy colliding hadrons/nuclei, and (5) quantumnon-abelian votex in dense QCD matter [17]

Research Subjects: Precision spectroscopy of exotic atoms and nuclei

Member: Ryugo S. Hayano and Takatoshi Suzuki

1) Antimatter study at CERN’s antiproton decelerator

Antiprotonic helium laser spectroscopy Atomic transition frequencies in antiprotonic helium (togetherwith those in hydrogen) yield information on the Rydberg constant and the proton-to-electron massratio, thereby contributing to the CODATA 2006 recommended values of the fundamental physicalconstants.

In order to further improve the antiprotonic helium laser spectroscopy precision, we have devel-oped new Doppler-free spectroscopy methods with which it should be possible to determine the(anti)proton-to-electron mass ratio with a relative standard uncertainty better than 10−10 (i.e., bet-ter than the current CODATA value) within a few years.

Antihydrogen Spectroscopic comparison of hydrogen and antihydrogen (p − e+) atoms is considered tobe one of the most stringent test of the CPT symmetry. At CERN, we can now routinely formantihydrogen atoms by mixing antiprotons and positrons, and our current goal is to capture antihy-drogen atoms by using a superconducting octupole magnet system. At the same time, developmentof an “antihydrogen beam”, with which we plan to measure the antihydrogen ground-state hyperfinesplitting, is in progress.

p-nucleus annihilation cross section at ultra-low energies At high energies, it is known that the p-nucleus annihilation cross sections scale as σann ∝ A2/3 where A is the nuclear mass number. However,at very low energies, this scaling is expected to be violated, but no such measurements have been donedue to the lack of ultra-low-energy antiproton beams. Using a radio-frequency quadrupole decelerator(“inverse linac), we have started the σann measurements at 100 keV. In 2010, we developed a beam

224

3. HAYANO GROUP

profile monitor for the ultra-low-energy antiproton beams, and succeeded in precisely guiding thebeams to our targets using this monitor and ion-optical calculations. We are now developing detectorsto measure the cross sections, and we will carry the measurement of the p-nucleus annihilation crosssections.

2)Laser spectroscopy of radioactive francium isotopes at the ISOLDE facility

at CERN

Laser spectroscopy is a crucial tool for studying properties of nuclear ground states. At the ISODLEfacility at CERN, the new CRIS collaboration of Manchester, Leuven, Birmingham, Orsay, Max PlanckInstitute of Quantum Optics, and Tokyo has proposed to measure the isotope shifts and hyperfine structuresof francium isotopes by collinear resonant ionization spectroscopy (CRIS). The CRIS method may provideevidence of the anomalous structure in neutron deficient francium isotopes.

For the CRIS method, we plan to use a nanosecond titanium-sapphire laser developed by the ASACUSAexperiment at CERN. This laser will be operated with a high output power of ∼kW and a narrow linewidthof 100 MHz, and thus allow the measurement of the isotope shifts (∼10 GHz) and hyperfine structures(∼100 MHz) of francium isotopes with relatively low yields (several ions/s). In 2010, we have started toset up the laser for the experiment in 2011.

3) Precision X-ray spectroscopy of kaonic atoms

The X-ray spectroscopy of kaonic atoms is a complementary tool to study kaon-nucleon/nucleus interac-tion. The advent of a new type of high-resolution x-ray detector, SDD, its combination with high-intensitybeamline provides clean kaon beam and various trackers/counters technique, enables us to study kaonicatoms with unprecedented precision.

X-ray spectroscopy of kaonic atoms at DAΦNE In fiscal year 2010, we analyzed the data of hydro-gen and helium-3 target measurement carried out during the beam time of SIDDHARTA experimentin fiscal year 2009. For kaonic hydrogen atom, we are finalizing the conclusion on its 1s-level shiftand width with respect to the energy level determined only by the electromagnetic interaction. Theresult will be published in the coming months. On the other hand, from the first measurement ofkaonic helium-3 X-ray in SIDDHARTA experiment, we determined with a precision of less than 10eV that the 2p-level shift of kaonic helium-3 atom is a small one close to zero. To establish a con-crete conclusion on the 2p-level shift of kaonic helium-3 atom, the result from E17 experiment underpreparation at J-PARC is necessary.

X-ray spectroscopy of kaonic helium at J-PARC The 2p-level shifts in kaonic helium 3 and kaonichelium 4, and the isotopic shift between them give a strong constraint to the kaon-nucleas interaction.A recent x-ray measurement by SIDDHARTA group implied a finite isotopic shift which can not beexplained by the optical model framework. Then, the J-PARC E17, which is the first experiment tobe carried out at K1.8BR beamline in the J-PARC hadron experimental facility, is now proposingkaonic helium 4 measurement, in addition to the originally proposed kaonic helium 3 measurement,to precisely determine the isotopic shift. In fiscal year 2010, we proceeded the kaon beam tuning ofK1.8BR beamline and succeeded in operating SDDs (silicon drift x-ray detectors) under the beamcondition . The damage to our detectors by the earthquake is limited and the E17 is expected to runsoon after the recovery of the facility.

4) Study of kaonic nuclei

Study of kaonic nucleus via the stopped K− reaction on helium 4 In FSY 2005, we have performedKEK-PS E549, to measure (semi-)inclusive 4He(K−

stopped, N) spectra, and obtained strict upper

limits for the formation of narrow KNNN states with total isospin T = 0/1. Meanwhile, the4He(K−

stopped, Y N/Y d) semi-exclusive spectra exhibitted unresolved wide strengths which are well

separable from multi-nucleon processes. They could be the signal of non-mesonic Y N/Y NN decay of

225

4. OZAWA GROUP

strongly-bound KNN/KNNN states. In FSY 2010, we have further identified Σ0NNN final statesby the study of ΛNN triple coincidence events, and found that the proton momentum spectrum fromthe final states is clearly deviated from the one expected from the two-nucleon absorption process,and most likely to be the signal of those multibaryonic states. As a byproduct, we have identified the

four-nucleon absorption process of K− meson at rest, K−4He → Λt for the first time.

Search for K−pp and K−pn deeply-bound kaonic states at J-PARC The J-PARC E15, to be sched-uled after E17 at K1.8BR beamline, will use the 3He(K−, N) reaction to search for K−pp/K−pn.E15 is a kinematically complete experiment in which all reaction products are detected exclusivelyespecially for K−pp → Λp channel, and it aims to provide decisive information on the nature of thesimplest kaonic nucleus. In FSY 2010, we have installed the Cylindrical Drift Chamber (CDC) intothe solenoid magnet, tested the performance of the system (Cylindrical Detector System - CDS) withthe activated magnetic field, and performed the CDS calibration with 0.9 GeV/c K− beam, so thatΛ → pπ− and K0

s → π+π− reactions were successfully reconstructed.

5) Precision spectroscopy of pionic atoms

We are planning a precise pionic-atom spectroscopy experiment with BigRIPS at RIBF. The goal is tostudy 1s and 2s pionic states in 121Sn by the 122Sn(d,3He) reaction. The measurement will help us betterunderstand the strong interaction between the pion and the nucleus, which leads to quantitative evaluationof the magnitude of the quark condensate at the normal nuclear density.

In October 2010 we performed a pilot experiment to construct ion optics for the dispersion matchingwith the (d,3He) reaction and to check performance of the focal plane detectors which will be used in theproduction experiment. The beam was provided by the SRC with an energy of 250 MeV/nucleon andan intensity of ∼ 4 × 1011/s. This high intensity deuteron beam hits the target, 10 mg/cm2 122Sn, andproduces a large number of protons of ∼ 200 kHz as background at the focal plane.

We could construct the BigRIPS optics by using the 14N beam and the thick Cu target and confirmthe optics of the beam transfer line was consistent with the designed optics. We also confirmed that alldetectors worked with high intensity beam as we expected. We could measure the track with the designresolution by MWDCs and identify 3He in the large background of protons by TOF and energy loss ofscintillators.

6) Study of muonium production targets

Ultra-slow polarized muon beam whose energy of 0.5∼30keV is anticipated as a new “microscope formagnetism” for the investigation of the surface magnetism. The ultra slow muon beamline was establishedin the RIKEN RAL muon facility. In this site, 15∼20/s ultra-slow muons can be generated while initialmuon beam intensity reaches to 1.3 ×106 /s. In order to increase the intensity of the ultra-slow muons,improvements of the escaping efficiency of the muonium from the muonium formation target (3%), andlaser ionization (∼ 10−5) are needed. As for muonium formation target, silica-based or alumina-basedmaterials are promising. In order to develop the new muonium formation target, we fabricated samples of(i)Silica nanoporous plate(ii)Alumina nanoporous plate (iii)Silica Aerogel, and measured muon-muoniumconversion rate and muonium diffusion of them in TRIUMF. As a result, sample(iii) has muon-muoniumconversion rate of 70% compared to heat-tungsten foil(T= 3000 K) that have been used in RIKEN RALfacility. Meanwhile, energy of emitted muonium is comparable with thermal energy of room temperatureso that the density distribution of muonium around the target surface suppose to be higher than that ofconventional muonium target. In the next year, with a new laser system, we will perform practical test ofnew muonium production target in the RIKEN-RAL muon facility.

Study of quark-gluon-plasma at RHIC

In 10 years operation of Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory(BNL), many new phenomena related to hot and dense nuclear matter have been discovered. We performedthe PHENIX experiment at RHIC and produced many new results on a wide range of physics subjects,including charged and neutral hadron production, single electron production, event isotropy, and manyother topics.

In spite of these fruitful results, there are still remaining questions to be answered to further characterizethe state of matter formed at RHIC. In particular, chiral properties of the dense matter produced has notbeen obtained, and should be provided. For the study of the chiral properties, vector mesons, such as φ, ωand ρ are interesting mesons because the restoration of approximate chiral symmetry at high temperaturemay modify their mass and width. These modifications can be shown directly in the line shape of the e+e−mass spectra. Here, the measurements with lepton decays are essential, since leptons are not interact withthe medium and carry direct information about conditions and properties of the medium. However, largebackground in electron pairs due to π0 Dalitz decays and γ conversion make the measurement difficult inthe past RHIC data. In the last year, we have successfully installed and operated a new detector, which iscalled Hadron Blind Detector(HBD), to suppress the background.

In this year, we have focused on rejection of gamma conversions at HBD itself, since such conversionscan be a serious background in high multiplicity environment due to a scintillation light. As a result, wehave successfully developed analysis scheme to reject such background statistically.

Study of mechanism of hadronic mass generation at J-PARC

The chiral property of QCD in dense(ρ �= 0) nuclear matter has also attracted wide interest in the fieldof hadron physics. In hot and/or dense matter, broken chirtal symmetry is subject to be restored eitherpartially or completely and, hence, the properties of hadrons can be modified. To observe such an effect,measurements of the in-medium decay of vector mesons are highly desirable for the direct determinationof the meson properties in matter. We are planning two new experiments at J-PARC to measure vectormeson mass at normal nuclear density.

One new experiment aim to collect 100 times larger statistics of φ meson than that collected by the KEKexperiment. We can discuss the velocity dependence of the mass spectra of vector mesons more preciselyand compare with the theoretical predictions. We are also able to use larger and smaller nuclear targetsas lead and proton, For this experiment, new detector based on Gas Electron Multiplier (GEM), which isoriginally developed at CERN, is under developing. Using GEM, we are investigating 2 dimensional trackerfor high rate counting. A prototype is reconstructed and reasonable signals are observed.

In this year, large sizes (20cm and 30cm) of GEM foils are developed and tested. An test experiment isperformed at LNS test beam line at Tohoku Univ. Position resolutions of large size GEMs are evaluatedusing an electron beam. As shown in Fig. 2.1.5, a position resolution of 100 μm is obtained both for 20cm and 30 cm GEMs.

Also, we propose combined measurements of nuclear ω bound state and direct ω mass modification.Nuclear ω bound states are measured in p(π−, n)ω reaction and decays of generated ω meson are alsomeasured with ω → π0γ mode. Such exclusive measurement can supply essential information to establishpartial restoration of the chiral symmetry in nucleus.

We constructed TOF counters in this year and tested them at LEPS beam line at Spring-8 to evaluateits timing resolution and neutron efficiency. The timing resolution of 60 ps is obtained. Analysis for theneutron efficiency is on-going.

Tests of EM Calorimeter is performed at LNS GeV-γ beam line at Tohoku University. As a EM Calorime-ter, we are planning to use CsI crystals, which is used at KEK-E246. Photon readout on CsI crystal ischanged from Photo Diode to Avalanche photo diode to cope with high counting rate at J-PARC. Then,energy resolution of CsI crystal and Avalanche photo diode is evaluated using an electron beam. Resultsare shown in Fig. 2.1.6. Obtained energy resolution is enough for our purpose.

We, particle physicists, are entering an exciting period in which new paradigm of the field will be openedon the TeV energy scale by new discoveries expected in experiments at high-energy frontier colliders, LHCand ILC.

1) Preparation for the International e+e− Linear Collider ILC: ILC is the energy frontier machine fore+e− collisions in the near future. In 2004 August the main linac technology was internationally agreedto use superconducting accelerator structures. In 2007 March, the Reference Design Report was issued bythe Global Design Effort (GDE) and hence the project has been accelerated as an international big-scienceproject. The technical design will be completed in the end of 2012. We are working on ILC acceleratorrelated hardware development, especially on the beam delivery system. We are developing the Shintakebeam size monitor for the ATF2, which is a test accelerator system for ILC located at KEK. The Shintakebeam size monitor is able to measure O(10)[nm] beam size, by using a high power laser interferometer. Theelectron beam is emitted to the interference fringe of the split laser beams. The total energy of photons,which are emitted from the inversed Compton scattering of beam electrons with the laser beam interferencefringe, is measured by a multilayer CsI(Tl) detector in the down stream. The phase of the fringe is movedstep-by-step, the total photon energy is measured in each step, and the beam size is extracted from a fittingof modulation pattern of the total photon energy as a function of the phase. Also we have been studyingpossible physics scenario and the large detector concept (ILD) for an experiment at ILC.

2) Experiment for studying quantum bound states due to the earth’s gravitational potential and searchingfor new short-range force using ultra-cold neutron beam: A detector to measure gravitational bound statesof ultra-cold neutrons is developed. We decided to use CCD’s for the position measurement of the UCN’s.The CCD is going to be covered by a 10B layer to convert neutron to charged nuclear fragments. The UCNsare going through a neutron guide of 100 [μ] height and their density is modulated in height as formingbound states within the guide due to the earth’s gravity. In 2008 we tested our neutron detector at ILLGrenoble. In 2009 we started the test experiment at ILL. We are analyzing the data. We will improve ourdetector and measure the modulation of the neutron density distribution in 2011.

3) ATLAS experiment at LHC: The epoch of new paradigm for particle physics is going to open withthe experiments at LHC. LHC started its operation in the end of 2009. The high energy collision at 7 TeV(CMS) has been started in the end of March 2010. The ATLAS detector is continuously recording data athigh energies. Some of our students work on data analysis at LHC. Search for supersymmetric particleswith the missing transverse energy and with b-quark signal.

4) BES-II/-III experiment at IHEP: The group has considered the BES-III experiment at the Beijinge+e− collider BEPC-II as the candidate for the middle term project before ILC. We have made a researchand development for TOF detector for the BES-III experiment together with IHEP, USTC. We successfullycompleted a test of over 500 photomultipliers in 1[T] magnetic field and they are already installed to theBES-II detector. We have studied the data analysis of baryon-pair production in Jψ decay using 5.8MBES-II J/ψ events. Now BEPC-II is operating smoothly and BES-III detector is taking large samples ofψ′ and J/ψ data.

Various kinds of astro-/non-accelerator/low-energy particle physics experiments have been performedand are newly being planned in our research group.

We started a new R and D study of a compact mobile anti-electron neutrino detector with plasticscintillators to be used at a nuclear reactor station, for the purpose of monitoring the power and plutoniumcontent of the nuclear fuel. It can be used to monitor a reactor from outside of the reactor containment withno disruption of day-to-day operations at the reactor site. This unique capability may be of interest for thereactor safeguard program of the International Atomic Energy Agency(IAEA). We have built a prototypedetetctor of a size of 1700 × 667 × 551 mm3 and weight of 270kg. It is now deployed at Hamaoka NuclearPower Station of Chube Electric Power Co., Inc.

We are running an experiment to search for axions, light neutral pseudoscalar particles yet to be discov-ered. Its existence is implied to solve the so-called strong CP problem. The axion would be produced in thesolar core through the Primakoff effect. It can be converted back to an x-ray in a strong magnetic field inthe laboratory by the inverse process. We search for such x-rays coming from the direction of the sun withthe TOKYO AXION HELIOSCOPE, aka Sumico. Sumico consists of a cryogen-free 4T superconductingmagnet with an effective length of 2300 mm and PIN photodiodes as x-ray detectors. By now, we putupper limits of gaγγ < (5.6–13.4) × 10−10GeV−1 to axion - photon coupling constant for the axion massma < 0.27 eV and 0.84 eV < ma < 1.00 eV. The latter is a newly explored mass region which CERNAxion Solar Telescope(CAST) group that started later has not reached yet. We planned to continue themeasurement in which we scan the mass region from 1 eV upward.

An experiment is being performed for a search for hidden sector photons kinetically mixing with theordinary photons. The existence of the hidden sector photons and other hidden sector particles is predictedby extensions of the Standard Model, notably the ones based on string theory. The hidden sector photonis expected to come from the direction of the sun. It would be produced in the solar core or in the space byoscillation of the ordinary photon, and can transmute into the photon again in a long vacuum chamber inthe laboratory. A photon sensor in the chamber would readily detects the ordinary photon. The detectoris now ready and piggybacked onto the Sumico helioscope. We let the detector track the sun to searchfor the hidden sector photons coming from the sun and found no significant signal for the hidden sectorphoton. We put upper limits to the mixing angle χ of the normal photon and the hidden sector photon inthe unexplored parameter region around the hidden sector photon mass region around a few millielectronvolts. This is the world’s first solar hidden sector photon search experiment with a dedicated solar hiddensector photon telescope.

One of the major research activities in our group has been a study of CP-violation and a search forphysics beyond the Standard Model in the B meson and the τ lepton systems using the KEK B-factory(KEKB). This past year, we began a study of anomalous magnetic moment of the τ lepton, (g−2)τ , whichis sensitive to physics beyond the Standard Model. Using ∼ 900 million τ -τ pairs recorded with the Belledetector, we intend to improve a precision of (g − 2)τ measurement by a factor of ∼ 10 over previousmeasurements.

The Super KEKB project started in 2010. The upgraded accelerator, Super KEKB, will have 40 timesmore luminosity than KEKB. The Belle detector is also being upgraded as Belle II detector with cutting-edge technology. One of key elements for the success of Belle II will be the reduction and control of

the background from accelerator. We measured the background level of KEKB with a special run. Byextrapolating it to the Super KEKB condition with a simulation, we estimated the background level atBelle II. The optimization of interaction region is in progress based on our results.

As an observational cosmology project, we are involved in building a 1.2 Giga pixel CCD camera (HyperSuprime-Cam) to be mounted on the prime focus of the Subaru telescope. With this wide-field camera,we plan to conduct extensive wide-filed deep survey to investigate weak lensing. This data will be used todevelop 3-D mass mapping of the universe. It, in turn, will be used to study Dark Energy.

The T2K long baseline neutrino oscillation experiment started in April 2009. We have searched forνμ → νe oscillation using data collected from January to June 2010. One candidate of electron neutrinoevent is observed at the Super-Kamiokande detector, while 0.3 background events are expected. With moredata, we expect to lead the study of neutrino oscillation.

In order to pursue the study of properties of neutrino beyond T2K, we have started the design of nextgeneration water Cherenkov detector, Hyper-Kamiokande (HK). One of the main goals of HK is the searchfor CP violation in leptonic sector using accelerator neutrino and anti-neutrino beams. The sensitivity toCP violating phase is studied with full simulation. It is shown that with HK and J-PARC accelerator, CPviolation can be observed after five years of experiment for a large part of possible parameter space.

In order to reduce the uncertainty in the neutrino oscillation measurements, we have been analyzingdata from SciBooNE, an experiment performed at Fermilab to study neutrino-nucleus interaction. Wehave measured the cross section of the inclusive νμ charged current interaction on carbon. Using thismeasurement, we have also searched for neutrino oscillation together with MiniBooNE collaboration.

We have been developing hybrid photodetector (HPD) combining a large-format phototube technologyand avalanche diode as photo-electron multiplier. This year, we have developed 8-inch HPD with all glassdesign, together with a compact high voltage supply and readout electronics.

• (1) LHC (Large Hadron Collider) has the excellent physics potential. Our group is contributing tothe ATLAS group in the Physics analyses: focusing especially on three major topics, the Higgs boson,Supersymmetry and Extra-dimension.

– Higgs: We are focusing on Higgs boson whose masses is lighter than 140 GeV. H → γγ , ττand WW are the promising channels. We search for the Higgs with these three modes andNo evidence was observed. We need more luminosity for Higgs hunting and we can reach theluminosity of discovery within 2 years.

– SUSY: We contributes SUSY study at the ATLAS experiment as a convener. We have developedmethods of the data-driven background estimation for all channels, and we found out that wecan estimate background number//distributions from the data itself with accuracy of 10-30%even in the early of the state. Now we have real data and search for the SUSY with the variousevent topologies, and no evidence was observed in all topologies. We set stringent limit on thedark matter.

– Extra-dimension If the extra-dimension is compactified at a few TeV scale, Mini-black hole andKK excitation are interesting signals. We search for these topologies and we have set the limitof about 2TeV for the planck scale.

• (2) Small tabletop experiments have the good physics potential to discover the physics beyond thestandard model, if the accuracy of the measurement or the sensitivity of the research is high enough.We perform the following tabletop experiments:

1. Cooperative Phenomena and Phase TransitionStudy on phase transitions and critical phenomena is one of main subjects of the statistical mechanics.

We have studied various types of ordering phenomena in systems with large fluctuation. In the last year,we studied the following aspects of phase transitions. [1]

One is the phase transition in long-range Interacting systems. So far, phase transitions of spin systemshave been studied mainly on the fixed lattice. However, we pointed out that difference of local latticestructure, e.g. the sizes of the high-spin (HS) and the low-spin (LS) in the spin-crossover materials causeslattice distortions. This degree of freedom of lattice deformation causes an effective long range interactionfor ordering of bistable states. We have pointed out that the critical property of this type of models belongsto the universality class of the mean-field model, and also that its dynamical critical properties, such as thespinodal phenomena, are described by the corresponding mean-field theory. In the last year, in particular,we studied on the spatial ordering patterns of the system with long range interaction. In the long rangeinteraction system with periodic boundary condition, the system does not show compact ordering clustereven at the critical point in contrast to the usual short range systems in which the correlation lengthdiverges and infinite clusters appear. [41, 45] We studied how the correlation length changes if both shortand long range interactions exists. We derived a scaling relation of the correlation length as function ofthe ratio of the short and long range interactions, and confirmed by a Monte Carlo simulation. We alsostudied how switching between the two ordered state occurs in system with open boundary condition, andfound a scale-invariant property. [3, 4, 41, 45]

We also studied in which condition systems with long range interaction are described by the mean-fieldtheory. It is known that in the cases where the interaction energy per spin diverges, where the extensivityis not satisfied and the so-called Kac procedure is necessary, the thermal properties are described by themean-field theory if the order parameter is not conserved. We investigate the condition in detail, and

232

10. MIYASHITA GROUP

confirmed this property. Moreover, we found that even in this case, the properties in a fixed value of orderparameter cannot be described by the mean-filed theory in some parameter region. This indicates that theuniform configuration for the state of mean-field state becomes unstable inn such parameter region. Weare studying the properties of such states. [5, 31, 39]

Hiroko Tokoro made experimental studies on novel magnetic materials in collaboration with Ohkoshilaboratory (chemistry department). [6, 58, 59]

We also studies the general structure of the so-called mixed phase which has been found in the generalized6-state clock model with a quasi-degenerate energy structure. We found various new type phases and phasetransitions. [37, 43] We also studied on the classification of the first order phase transitions in the Pottsmodel with the so-called transparent states.

2. Quantum Statistical Mechanics

Cooperative phenomena in quantum systems are also important subject in our group. In quantum sys-tems, they show interesting non-classical behavior. We have studied quantum phase transitions in spinsystems and also itinerant electron systems. In particular, the mechanism of Nagaoka ferromagnetism pro-vides an interesting magnetic property in system where we control the chemical potential of the itinerantelectrons (Hubbard model). We proposed a system in which the transition between magnetic and non-magnetic state takes place with this mechanism and the property of the model is studied by the DMRGmethod. [50]

As a study on the exact solvable models, we studied the exact property of spin chain by making use ofalgebraic Bethe anzatz. In particular, we investigated properties of boundary states of S = 1 spin chain.[22, 23, 26, 27, 28, 29] We also studied a nontrivial symmetry in a one-dimensional S = 1 bilinear-biquadraticmodel by an exact diagonalization method. [57].

We also studied the dynamical properties and also response. Coherent dynamics of quantum systemshas also various characteristic features, and attracts interests from the view point of quantum informationprocessing. We have studied such novel quantum phases and quantum responses. [2] Parts of the subjectare studied as an activity of the JST CREST project (Quantum-mechanical cooperative phenomena andtheir applications). [47]

Quantum response to external fields is one of the important subjects in our group, and we have studiedresonant spectrum of interacting system by proposing a direct numerical method for the Kubo formula, andextended it to systems with dissipative dynamics.[48, 49] In the last year, we studied the line spectrum ofa spin chain with an alternative Dzyaloshinsky-Moriya interactions at high temperature limit, and analyzedit in the relation with the autocorrelation function of the spin torque which shows a deviation from thegaussian relaxation at long time. We discussed an extension of the Kubo-Tomita theory. [7]

We also studied hybridization of a spin system in the cavity and the cavity photon which attracts interestsfrom the view point of coupling of photon information and materials. We published a paper with the relatedexperiments[8], which has been reviwed as a possible realization of the Quantum RAM. We extended thestudy to detailed structure of the line shape by studying the energy structure of hybridized systems.

Moreover, we studied origins of decoherence of the Rabi oscillation which is regarded as an evidence ofquantum coherence. We classified the characterization of the origins of the decoherence, e.g. the localdistribution of magnetic field and the magnetic anisotropy, and the dipolar-dipolar interactions among thespins, etc. We are applying it to the related experiments.

How the equilibrium (canonical distribution) is realized is also a big topic in statistical mechanics. Wehave study an isolated spin system and study the dynamics explicitly, and observed how the local systemapproaches to a stationary state and it is resemble to the canonical distribution as a function of strengthand type of the interaction between the local system and the rest system. [9]

We have studied quantum effect in the conveyance process of particle dragged by a potential well. Westudied origins of the non-adiabatic transition during the process, and analyzed them from the view pointsof the resonant state for systems with the quantum tunneling.[56]

We also studied dynamical properties of quantum systems under transverse field in the context of thequantum annealing. [10, 11]

On the duality between particle and wave in quantum mechanics, we studied in what condition we canrealize the wave nature in a model of particles. [12, 13]

As to the transport phenomena, we studied universal feature of the current fluctuation. We deriveda generated cumulant function and examine the proposal of the additivity principle of Derrida. We alsostudied the AC conductance of the heat conductivity. [14, 15, 16, 17, 18, 19, 20, 52, 53, 54, 55]

13. FUJIMORI GROUP

to develop and apply such techniques of computational physics to investigate basic problems in condensedmatter physics, especially focusing on prediction of material properties under extreme conditions like ultra-high pressure or at surfaces where experimental data are limited. Our principal tool is molecular dynamics(MD) and first-principles electronic structure calculation based on the density functional theory (DFT),while we are also developing new methods that go beoynd the limitation of classical MD and DFT.

In FY2010, we predicted theoretically novel two-dimensional interface ferromagnetism at AlN/MgB2(0001)using DFT calculations (Y. Gohda and S. Tsuneyuki, Phys. Rev. Lett. 106, 047201 (2011)). First-principles electron transport calculations demonstrate that this interfacial spin polarization is responsiblefor quantum spin transport. The magnetization can be controlled by applied gate bias voltages.

We also developed or improved several methodologies for first-principles study of electronic, structuraland dynamical properties of materials. One of the major achievements is that we obtained first convergedresults of the electronic structure calculation of a large-gap insulator by the Transcorrelated (TC) method,a wave funtion theory we have developed for several years.

In summary, our research subjects in FY2010 were as follows:

• New methods of electronic structure calculation

– Generalized anharmonic lattice model of crystals for investigating thermal conductivity

– First-principles wavefunction theory for solids based on the Transcorrelated method

– FMO-LCMO method: a new method of electronic structure calculation of huge biomoleculesbased on the fragment molecular orbital (FMO) method

• Applications of first-principles electronic structure calculation

– Two-Dimensional Intrinsic Ferromagnetism at Nitride-Boride Interfaces

1. Project and Research Goal

The striking features of low-dimensional electronic systems with strong correlations are the “fractional-ization” of an electron and the “self-organization” of electrons to form nanoscale orders. In one dimension(1D), an electron is fractionalized into two separate quantum-mechanical particles, one containing its charge(holon) and the other its spin (spinon). In two dimensions (2D) strongly correlated electrons tend to formspin/charge stripe order.

Our study focuses on 1D and 2D copper oxides with various configurations of the corner-sharing CuO4

squares. The common characteristics of such configurations are the quenching of the orbital degree offreedom due to degraded crystal symmetry and the extremely large exchange interaction (J) betweenneighboring Cu spins due to large d − p overlap (arising from 180 Cu-O-Cu bonds) as well as to thesmall charge-transfer energy. The quenching of orbitals tends to make the holon and spinon to be well-defined excitations in 1D with quantum-mechanical character, and the extremely large J is one of thefactors that give rise to superconductivity with unprecedentedly high Tc as well as the charge/spin stripeorder in 2D cuprates. The experimental researches of our laboratory are based upon successful synthesis ofhigh quality single crystals of cuprate materials with well-controlled doping concentrations which surpassesany laboratory/institute in the world. This enables us to make systematic and quantitative study of thecharge/spin dynamics by the transport and optical measurements on the strongly anisotropic systems. Wealso perform quite effective and highly productive collaboration with world-leading research groups in thesynchrotron-radiation, μSR and neutron facilities, and STM/STS to reveal electronic structure/phenomenaof cuprates in real- and momentum-space.

2. Accomplishment

(1) Ladder Cuprate

Significant progress has been made in the experimental study of a hole-doped two-leg ladder systemSr14−xCaxCu24O41 and undoped La6Ca8Cu24O41 :

1) From the high pressure (P) study we constructed and x-P phase diagram (in collaboration with Prof. N.Mori’s group). We find that the superconductivity appears as a superconductor-insulator transition onlyunder pressures higher than 3GPa and that the superconducting phase is restricted in the range of x largerthan 10. In lower P and smaller x regions the system is insulating.

2) The pairing wave function in the superconducting phase has an s-wave like symmetry which is evidencedby a coherence peak at Tc in the nuclear relaxation rate, revealed by the first successful NMR measurementunder high pressure.

3) The origin of the insulating phase dominating the whole x−P phase diagram is most likely the chargeorder of doped holes or hole pairs as suggested by the presence of a collective charge mode in the x=0,Sr14Cu24O41, compound in the inelastic light scattering (with G. Blumberg, Bell Lab.), microwave andnonlinear conductivity (with A. Maeda and H. Kitano, U. of Tokyo), and inelastic X-ray scattering (withP. Abbamonte and G. A. Sawatzky).

4) In the undoped compound La6Ca8Cu24O41 spin thermal conductivity is remarkably enhanced to thelevel of silver metal along the ladder-leg direction due to the presence of a spin gap and to a ballistic-likeheat transport characteristic of 1D.

(2) Observation of Two Gaps, Pseudogap and Superconducting Gap, in Underdoped High-Tc

Cuprates.

The most important and mysterious feature which distinguishes cuprate from conventional superconduc-tors is the existence of pseudogap in the normal state which has the same d-wave symmetry as thesuperconducting gap does. We employed c-axis optical spectrum of Yba2Cu3O6.8 as a suitable probe forexploring gaps with d-wave symmetry to investigate the inter-relationship between two gaps. We find thatthe two gaps are distinct in energy scale and they coexist in the superconducting state, suggesting that thepseudogap is not merely a gap associated with pairs without phase coherence, but it might originate froma new state of matter which competed with d-wave superconductivity.

(3) Nanoscale Electronic Phenomena in the High-Tc Superconducting State

The STM/STS collaboration with J. C. Davis’ group in Cornell Univ. is discovering numerous unexpectednanoscale phenomena, spatial modulation of the electronic state (local density of states, LDOS), in thesuperconducting CuO2 planes using STM with sub-A resolution and unprecedentedly high stability. Theseinclude (a) “+” or “×” shaped quasiparticle (QP) clouds around an individual non-magnetic Zn (magneticNi) impurity atom, (b) spatial variation (distribution) of the SC gap magnitude, (c) a “checkerboard”pattern of QP states with four unit cell periodicity around vortex cores, and (d) quantum interference ofthe QP. This year’s highlights are as follows:

1) Granular structure of high-Tc superconductivity

The STM observation of “gap map” has been extended to various doping levels of Bi2Sr2CaCu2O8+δ. Theresult reveals an apparent segregation of the electronic structure into SC domains of ∼3mm size with localenergy gap smaller than 60meV, located in an electronically distinct background (“pseudogap” phase) withlocal gap larger than 60meV but without phase coherence of pairs. With decrease of doped hole density, the(coverage) fraction of the superconducting area decreases or the density of the number of superconductingislands decreases. Apparently, this is related to the doping dependence of superfluid density as well as thedoping dependence of the normal-state carrier density.

2) Homogeneous nodal superconductivity and heterogeneous antinodal states

Modulation of LDOS is observed even without vortices, at zero magnetic field. In this case, the mod-ulation is weak and incommensurate with lattice period, showing energy (bias voltage) dependence. Thedispersion is explained by quasiparticle interference due to elastic scattering between characteristic regionsof momentum-space, consistent with the Fermi surface and the d-wave SC gap determined by ARPES(angle-resolved-photoemission).

These dispersive quasiparticle interference is observed at all dopings, and hence the low-energy states,dominated by the states on the Fermi arc formed surrounding the gap nodes, are spatially homoge-neous(nodal superconductivity). By contrast, the quasiparticle states near the antinodal region degradein coherence with decreasing doping, but have dominant contribution to superfluid density. This suggeststhat the volume fraction of spatial regions all of whose Fermi surface contributes to superfluid decreaseswith reduced doping. The result indicates the special relationship between real-space and momentum-spaceelectronic structure.

16 Group

Research Subjects: Low Temperature Physics (Experimental):

Quantum fluids and solids with strong correlations and frustration,

Scanning tunneling microscopy and spectroscopy of two dimensional electron

systems and superconductors.

Member: Hiroshi Fukuyama, Tomohiro Matsui

Our current interests are (i) quantum phases with strong correlations and frustration in two dimensional(2D) helium three (3He), (ii) novel phenomena related to Graphene, monatomic sheet of carbon atoms. Weare investigating these phenomena at ultra-low temperatures down to 50 μK, using various experimentaltechniques such as NMR, calorimetry, scanning tunneling microscopy and spectroscopy (STM/STS), lowenergy electron diffraction (LEED) and transport measurement, etc.

1. Ground-state of two dimensional 3He:

It is an interesting open question to ask whether the critical point, i.e., the gas-liquid transition,exists in strictly 2D 3He. The previous quantum many-body calculations predict interestingly that3He has the critical point but 4He does not in pure 2D case. We have measured low-temperature heatcapacities (C) of the second-, third- and fourth-layer 3He adsorbed on a graphite surface preplated

with monolayer 4He to elucidate if the ground state of each layer is gas or liquid phase. The elucidationis based on the fact that the coefficient (γ) of T -linear term in C(T ) in degenerated fermion system isdetermined by the surface area over which the fermions spread and the quasi-particle effective mass.It had been found until last year that there is the critical point over third layer and 3He atoms form2D paddles at low densities (ρ < 1.5 nm−2). This year, we found that even the second layer, where theconfinement potential from the substrate is stronger, does not have the critical point, too. Moreover,the density of the 2D paddle is comparable with that in third layer. Therefore, we can conclude thatthe ground state of 2D 3He is the liquid phase, and that the interaction between 3He atoms in 2D isattractive in average.

2. Other ongoing experiments on 2D 3He:

We are preparing a new sample cell for high-precision heat capacity measurements of the possibleorder-disorder transition near T = 1 K in the second layer 3He on graphite using a ZYX exfoliatedgraphite substrate which has much larger micro-crystalline size than the previous one. The purposeof this experiment is to confirm the existence of such a commensurate phase, the 4/7 phase, at theexpected density around which many interesting quantum phenomena are proposed to emerge atlow temperatures. Designing of a LEED (low energy electron diffraction) experiment below 0.5 K isalso undergoing in order to determine the structures of the commensurate phase unambiguously. Acryogen-free dilution refrigerator which will be used for these next generation experiments has beentested successfully with the lowest temperature of 12 mK and the cooling power of 200 μW at T = 100mK.

3. Kosterlitz-Thouless transition of the Sn island network on Graphene:

Since graphene is fabricated on top of a substrate, one can directly couple dopants with two di-mensional electron gas in graphene, whose carrier density and type can be tuned by an appliedgate voltage. Thus, graphene could provide an ideal substrate for study of proximity effect. Actually,graphene has been shown to effectively carry proximity-induced Josephson currents injected from con-tacting electrodes. On the other hand, it has also known that elemental superconductor Sn readilyform self-assembled islands when deposited on graphene at room temperature. Therefore, Sn islandson graphene is a good candidate to study the superconducting proximity effect and 2D Josephsonjunction network.

The graphene samples are prepared by exfoliating Kish graphite onto SiO2 substrate. Sn is depositedon graphene with photo-lithographed electrodes in high vacuum, and their transport properties aremeasured at temperatures down to 0.5 K and in magnetic fields up to 9 T. A sample with Sn ofnominally 30 nm thick actually shows islands with about 300 nm diameter and about 20 nm separationin scanning electron microscope image. The temperature dependence of the resistance shows twotypes of superconducting transitions. The resistance drops suddenly with decreasing temperatureat T ∼ 3.9 K reflecting the superconducting transition of Sn islands. At 2.0 K < T < 3.9 K,the resistance shows exp(−1/

√T ) dependence suggesting Kosterlitz-Thouless (KT) superconducting

transition in 2D. From this analysis, KT transition temperature TKT is estimated to be 2.06 K. Theresistance does not become zero and gradually decreases with decreasing temperature at T < 2.0K, that is presumably because of the finite size effect, since there estimated to be only 6 islands inbetween electrodes. In magnetic fields of B > Bc = 77 mT, the slope of the temperature dependencechanges its sign from metallic to insulating. In addition, the resistance shows thermally activated 1/Tdependence in B < Bc. These results suggest the field induced superconductor-insulator transitionin this superconducting Sn network on graphene.

4. Band gap tuning in functionalized Graphene:

Graphene has a gapless band structure, and it is importand for graphene electronics to engineer aband gap in this material. Since the gapless character in graphene is protected by the high symmetryof its lattice, in which two carbon sites in the unit cell are equivalent, the simplest way of gap-openingis to lift the symmetry. One of the approaches to modify the electronic properties is to functionalizethe graphene by atom deposition. It is expected that there would be a energy gap with enhanceddensity of states (DOS) when adatoms form ordered structure on graphene. To experimentaly confirm

this property, we preliminary studied the DOS of Xe atom adsorbed on graphite with STS. We foundthat a energy gap with an order of ±1 V is created when the Xe form a

3 adsorbed structure.

Research Subjects: Experimental Condensed Matter Physics,

Low temperature electronic properties of two-dimensional systems.

Member: Tohru Okamoto and Ryuichi Masutomi

We study low temperature electronic properties of semiconductor two-dimensional systems.

The current topics are following:

1. Two dimensional electrons at cleaved semiconductor surfaces:At the surfaces of InAs and InSb, conduction electrons can be induced by submonolayer depositionof other materials. Recently, we have performed in-plane magnetotransport measurements on in-situcleaved surfaces of p-type substrates and observed the quantum Hall effect which demonstrates theperfect two dimensionality of the inversion layers. Research on the hybrid system of 2D electronsand adsorbed atoms has great future potential because of the variety of the adsorbates as well as theapplication of scanning probe microscopy techniques.

In 2010, we have modified our experimental setup in order to mount a scanning tunneling microscope.

2. Superconductivity of ultrathin Bi films on cleaved GaAs surfaces:We have performed magnetotransport measurements on ultrathin Bi films on GaAs(110) surfaces.To reduce disorder arising from the substrate, we used cleaved surfaces of insulating GaAs. Thecritical film thickness for superconductivity was obtained to be 0.42 nm, which is thinner than theprevious data for different kinds of substrates. In the study of I − V characteristics, we observeddiscontinuous jump in the temperature dependence of the power α in V ∝ Iα, which is associatedwith “universal jump” of the Kosterlitz-Thouless transition. This indicates that the KT transitioncan occur in amorphous films as well as Josephson-coupled arrays.

3. Strongly correlated two dimensional systems:Cyclotron resonance of two-dimensional electrons is studied at low temperatures down to 0.4 Kfor a high-mobility Si/SiGe quantum well which exhibits a metallic temperature dependence of dcresistivity ρ. The relaxation time τCR shows a negative temperature dependence, which is similarto that of the transport scattering time τt obtained from ρ. The ratio τCR/τt at 0.4 K increases asthe electron density Ns decreases, and exceeds unity when Ns approaches the critical density for themetal-insulator transition. [R. Masutomi et al., Phys. Rev. Lett. (accepted for publication).]

18 Shimano Group

Research Subjects: Optical and Terahertz Spectroscopy of Condensed Matter

Member: Ryo Shimano and Shinichi Watanabe

We study light-matter interactions and many body quantum correlations in solids. In order to investigatethe role of electron and/or spin correlations in the excited states as well as the ground states, we focuson the low energy electromagnetic responses, in particular in the terahertz(THz) (1THz∼4meV) frequencyrange where quasi-particle excitations and various collective excitations exist. The research summary inthis year is as follows.

240

19. THEORETICAL ASTROPHYSICS GROUP

1. High density electron-hole system: We investigated the thermodynamics of high density electronand hole(e-h) system in Si by optical pump and terahertz probe experiments. Through the observationof 1s-2p transition of excitons at 3 THz, we revealed the cooling dynamics of the e-h system and alsothe formation dynamics of excitons. Towards the realization of quantum degenerate phases such asexciton Bose Einstein condensation and e-h BCS phase, an essential difficulty exists in indirect gapsemiconductors, i.e., the spontaneous condensation of e-h system into e-h droplets(EHD). To overcomethis difficulty, we developed a pressure anvil cell that can apply uniaxial stress to the crystal so thatthe formation of EHD is suppressed. We also studied the fine structures of excitons in Si underthe magnetic field. Zeeman and diamagnetic shift of excitons are clearly observed through the1s-2pexciton transitions. By applying the magnetic field, accumulation of excitons into the spin- forbiddenlowest energy state is observed.

2. Optical Hall effect: We investigated the optical(terahertz frequency) Hall effect in: 1) 2-dimensionalelectron gas(2DEG) system of a GaAs/AlGaAs heterostructure in the integer quantum Hall regime,and 2) itinerant ferromagnet SrRuO3, by using highly sensitive THz polarization spectroscopy tech-nique. In the 2DEG system, the optical Hall conductivity σxy(ω) exhibits a plateau-like behavioraround the Landau-level filling ν = 2, indicating that the carrier localization effect, a crucial in-gredient in the integer QHE, affects the optical Hall conductivity even in the THz regime. In aSrRuO3 film, we studied the THz frequency anomalous Hall effect(AHE) and determined σxy(ω)from the Faraday rotation spectrum. A resonant structure was observed in σxy(ω) spectrum, whichis reasonably accounted for by the Berry phase theory of AHE.

3. Study of electromagnon in multiferroics: Electric active magnetic excitation, termed elec-tromagnon, has been proposed in multiferroic TbMnO3 as a collective excitation in a ferroelectricspin-spiral phase, but their origin had been controversial. We performed comprehensive study ofelectromagnon in rare earth manganite RMnO3(R=Dy, Tb, EuY) by THz time-domain spectroscopyand experimentally clarified two types of electromagnon, arising from 1) symmetric(si · sj) and 2)anti-symmetric(si × sj) exchange interaction between the neighboring Mn spins.

4. Development of intense THz light source: We developed an intense THz light source with thepeak electric-field amplitude as large as 0.9 MV/cm, by using optical rectification of femtosecond laserpulses in a LiNbO3 crystal. By using the developed intense THz pulses, we have demonstrated; 1)dynamical Stark effect of excitons in carbon nanotubes, 2) THz field-acceleration of carriers in carbonnanotubes that results in impact excitation of excitons, 3) THz pulse-induced melting of charge-orderin a quasi-2D organic conductor θ−(BEDT-TTF)2CsZn(SCN)4.

The Theoretical Astrophysics Group carries out a wide range of research programmes. However, astro-physics is a very broad field of research, and it goes without saying that our group alone cannot coverall the various important astrophysical research topics on hand. Among others we place emphasis on the“Observational Cosmology”.

“Observational Cosmology” attempts to understand the evolution of the universe on the basis of theobservational data in various wavebands. The proper interpretation of the recent and future data providedby COBE, ASCA, the Hubble telescope, SUBARU, and large-scale galaxy survey projects is quite importantboth in improving our understanding of the present universe and in determining several basic parametersof the universe which are crucial in predicting the evolutionary behavior of the universe in the past andin the future. Our current interests include nonlinear gravitational evolution of cosmological fluctuations,formation and evolution of proto-galaxies and proto-clusters, X-ray luminosity and temperature functions ofclusters of galaxies, hydrodynamical simulations of galaxies and the origin of the Hubble sequence, thermalhistory of the universe and reionization, prediction of anisotropies in the cosmic microwave backgroundradiation, statistical description of the evolution of mass functions of gravitationally bound objects, andstatistics of gravitationally lensed quasars.

Quantum information processing seeks to perform tasks which are impossible or not effective with theuse of conventional classical information, by using quantum information described by quantum mechanicalstates. Quantum computation, quantum cryptography, and quantum communication have been proposedand this new field of quantum information processing has developed rapidly especially over the last 15years. Entanglement is nonlocal correlation that appears in certain types of quantum states (non-separablestates) and has become considered as a fundamental resource for quantum information processing. In ourgroup, we investigate new properties of multipartite and multi-level entanglement and the use of theseproperties as resources for quantum information processing. Our current projects are the following:

• Distributed quantum information processing

21.1 Quantum States of Ultracold Atoms

Bogoliubov theory and Lee-Huang-Yang corrections in spin-1 and spin-2 Bose-Einstein con-

densates in the presence of the quadratic Zeeman effect

We develop Bogoliubov theory of spin-1 and spin-2 Bose-Einstein condensates (BECs) in the presence ofa quadratic Zeeman effect, and derive the Lee-Huang-Yang (LHY) corrections to the ground-state energy,pressure, sound velocity, and quantum depletion. We investigate all the phases of spin-1 and spin-2 BECsthat can be realized experimentally.We also examine the stability of each phase against quantum fluctuationsand the quadratic Zeeman effect. Furthermore, we discuss a relationship between the number of symmetrygenerators that are spontaneously broken and that of Nambu-Goldstone (NG) modes. It is found that inthe spin-2 nematic phase there are special Bogoliubov modes that have gapless linear dispersion relationsbut do not belong to the NG modes.

Quasi-Nambu-Goldstone Modes in Bose-Einstein Condensates

We show that quasi-Nambu-Goldstone (NG) modes, which play prominent roles in high energy physicsbut have been elusive experimentally, can be realized with atomic Bose-Einstein condensates. The quasi-NG modes emerge when the symmetry of a ground state is larger than that of the Hamiltonian. Whenthey appear, the conventional vacuum manifold should be enlarged. Consequently, topological defects thatare stable within the conventional vacuum manifold become unstable and decay by emitting the quasi-NGmodes. Contrary to conventional wisdom, however, we show that the topological defects are stabilized byquantum fluctuations that make the quasi-NG modes massive, thereby suppressing their emission.

Spontaneous magnetic ordering in a ferromagnetic spinor dipolar Bose-Einstein condensate

We study the spin dynamics of a spin-1 ferromagnetic Bose-Einstein condensate with magnetic dipole-dipole interaction (MDDI) based on the Gross-Pitaevskii and Bogoliubov theories. We find that variousmagnetic structures such as checkerboards and stripes emerge in the course of the dynamics due to thecombined effects of spin-exchange interaction, MDDI, quadratic Zeeman and finite-size effects, and nonsta-tionary initial conditions. However, the short-range magnetic order observed by the Berkeley group [Phys.Rev. Lett. 100, 170403 (2008)] is not fully reproduced in our calculations; the periodicity of the orderdiffers by a factor of 3 and the checkerboard pattern eventually dissolves in the course of time.

Hydrodynamic equation of a spinor dipolar Bose-Einstein condensate

We introduce equations of motion for spin dynamics in a ferromagnetic Bose-Einstein condensate withmagnetic dipole-dipole interaction, written using a vector expressing the superfluid velocity and a complexscalar describing the magnetization. This simple hydrodynamical description extracts the dynamics of spinwave and affords a straightforward approach by which to investigate the spin dynamics of the condensate. Todemonstrate the advantages of the description, we illustrate dynamical instability and magnetic fluctuationpreference, which are expressed in analytical forms.

Nonuniversal Efimov Atom-Dimer Resonances in a Three-Component Mixture of 6Li

The Efimov states are universal trimer states in a three-body system with resonant two-body interactions.We measured the magnetic-field dependence of the atom-dimer loss a three-component mixture of 6Li atoms,and observed two enhanced atom-dimer loss at 602 G and 685 G. These loss peaks correspond to thedegeneracy points of the energy levels of dimers and the Efimov stetaes, and the number of peaks indicatesthe existence of the ground and first excited Efimov trimers. We also found that the locations of thesepeaks disagree with universal theory predictions, in a way that cannot be explained by non-universal 2-body properties. We constructed theoretical models that characterize the non-universal three-body physicsof three-component 6Li atoms with a monotonic-energy-dependent three-body parameter. This result waspublished in Physical Review Letters in 2010.

21.2 Quantum Information, Quantum Measurement, and Information ther-

modynamics

Experimental realization of the Szilard engine [Nature Physics 6, 988-992 (2010)]

In 1929, Leo Szilard proposed a model of ”Maxwell’s demon,” which converts the obtained informationto the free energy (or the work) by feedback control. We have demonstrated the experimental realization ofthe Szilard engine for the first time. We performed a real-time feedback control on a single colloidal particleof the submicron scale at the room temperature. As a result, we succeeded to increase the particle freeenergy by the feedback control, and observed that the free-energy increase was larger than the input work.We have also experimentally verified the generalized Jarzynski equality, which was theoretically proposedby us. This work was the collaboration with the Muneyuki group (Chuo Univ.) and the Sano group (Univ.Tokyo), was published in Nature Physics, and was highlighted by News and Views.

Theoretical analysis of the quantum Szilard engine [Phys. Rev. Lett. 106, 070401 (2011)]

We theoretically studied the quantum version of the Szilard engine with multi particles. As a result, wederived the general formula that gives the work that can be extracted from the engine. In particular, wefound the quantum effect for the case of the single quantum particle, in which we need a positive amountof work to insert a barrier to the engine. We also found that the identical-particle effect is observed forthe multi particle case. For example, the amount of work that can be extracted from the Bosonic engineis larger than the work from the Fermionic engine. The quantum work was shown to converge to the

classical work with distinguishable particles. This work was published in Physical Review Letters, selectedfor Editor’s suggestion, and featured by Physics Viewpoint.

22 Makishima Group & Nakazawa Group

Research Subjects: High Energy Astrophysics with Energetic Photons using Scientific

Satellites, Development of Cosmic X-Ray/γ-Ray Instruments

Member: Kazuo Makishima, Kazuhiro Nakazawa

Using space-borne instruments such as Suzaku and MAXI, we study cosmic high-energy phenomena inthe X-ray and γ-ray frequencies. We have been deeply involved in the development of the Hard X-rayDetector (HXD) onboard Suzaku, and are developing new instruments for future satellite missions.

Mass Accreting Black Holes: Mass accretion onto black holes provides a very efficient way of X-rayproduction. Confirmed black holes have masses in the range from several to several billion solar masses.Utilizing wide-band Suzaku spectra, we have shown that the matter accreting onto stellar-mass black holesand active galactic nuclei [3] both forms inhomogeneous hot “corona” that Comptonizes soft photons intohard X-rays. Evidence for rapid black-hole rotation, claimed by some foreign researchers, is consideredrather inconclusive or doubtful [5].

Neutron Stars with Various Magnetic Fields: Using Suzaku, we are studying neutron stars with avariety of magnetic field strengths, B. The least magnetized ones with B < 109 G, known as X-ray burstsources, behave rather similarly to stellar-mass black holes. Ordinary binary X-ray pulsars have B ∼ 1012

G, as estimated via the detection of electron cyclotron absorption lines. Some “fast transient” objects mayhave B ∼ 1013 G. Finally, we have revealed that about 10 “magnetars”, supposed to have B = 1014−15

G, emit unusual hard X-ray components, extending to ∼ 100 keV with very flat spectra [2]. We speculatethat the magnetism of neutron stars is a manifestation of ferromagnetism in nuclear matter.

Plasma Heating and Particle Acceleration: The universe is full of processes of plasma heating andparticle acceleration. In fact, the most dominant known component of cosmic baryons exists in the formof X-ray emitting hot (∼ 108 K) plasmas associated with clusters of galaxies. There, large-scale magneticstructures, and their interactions with moving galaxies, are considered to be of essential importance [4].

White Dwarfs and the Galactic Ridge Emission: From the 1980’, an apparently extended X-rayemission, called Galactic Ridge X-ray Emission, was known to distribute along our Galactic plane. UsingSuzaku, we have shown that this phenomenon can be considered, at least in energies above ∼ 10 keV, asan assembly of X-ray emission from numerous mass-accreting magnetic white dwarfs. This is supportedby a close resemblance between the Galactic Ridge X-ray Emission spectra and those of nearby individualwhite dwarf binaries [1].

Future Instrumentation: In collaboration with many domestic and foreign groups, we are develop-ing a successor to Suzaku, ASTRO-H. Scheduled for launch in 2014, it will conduct hard X-ray imagingobservations, high-resolution X-ray spectroscopy, and low-energy gamma-ray observations. We contributeto the development of two onboard instruments, the Hard X-ray Imager and the Soft Gamma-ray De-tectors. Our effort includes the development of “SpaceWire” technology, large BGO scintillators, andmechanical/thermal designs of the instruments.

Thermonuclear fusion, the process that powers the sun and stars, is a promising candidate for generatingabundant, safe, and clean power. In order to produce sufficient fusion reactions, isotopes of hydrogen, inthe form of hot and dense plasma, must be confined for a long enough time. A magnetic configurationcalled the tokamak has reached the level where the International Thermonuclear Experimental Reactor(ITER) is being constructed to study the behavior of burning plasmas. However, improvement of thecost-effectiveness of the fusion reactor is still necessary. The spherical tokamak (ST) offers a promisingapproach to increasing the efficiency by raising the plasma beta (the ratio of plasma pressure to magneticpressure). High beta plasma research using ST is a rapidly developing field worldwide, and is being carriedout in our group using the TST-2 spherical tokamak. TST-2 is now located in a new experimental buildingin Kashiwa Campus. Our group is tackling the problem of creating and sustaining ST plasmas using radiofrequency (RF) waves.

In TST-2 RF power is used to form the initial ST plasma and to ramp up the plasma current Ip. Previousexperiments have demonstrated plasma start-up using RF powers at 2.45GHz (ECH) and/or 21MHz. RFwaves at 200MHz were excited with either symmetric or asymmetric wavenumber spectrum (standing waveor travelling wave). With 200MHz RF power, the lower limit of magnetic field strength for plasma start-upcould be extended downward by roughly a factor of three compared to ECH. Ip ramp-up to 12 kA wasachieved with the travelling wavenumber spectrum in combination with a slowly increasing vertical field,compared to typical levels of 1–2 kA achievable with the symmetric spectrum. When the wave-driven currentis in the same direction as Ip, a stable ST configuration is obtained, but when the wave-driven current is inthe opposite direction a large Ip modulation (transition between two states) was observed. The asymmetricbehavior observed with travelling waves launched in opposite directions indicates that the contribution ofwave-driven current is significant. A build-up of energetic electrons as Ip is ramped up, observed by hardX-ray spectroscopy, also indicates the importance of the wave-driven current. The plasma configurationwas reconstructed based on magnetic measurements. Two representative equilibria were obtained, onewith centrally peaked current density profile, and the other with a peak near the outboard boundary. WithECH, both types are observed depending on the gas pressure. Only the outboard peaked current densityprofile was obtained by RF with symmetric spectrum, whereas centrally peaked current density profile wasalso obtained by RF with travelling spectrum. These profiles are probably manifestations of the differentRF power deposition profiles. RF power (200MHz) was also excited in inductively formed plasmas withIp � 100 kA. No conclusive evidence of current drive or heating has been observed with up to 130 kW of RFpower. This is most likely due to the low magnetic field (0.1T) used in this experiment. For the toroidalmode number (18) of the excited wave and the plasma density (1018 m−3) measured near the antenna,higher magnetic fields (0.3T) are needed for the excited wave to reach the plasma core, based on numericalmodelling of RF waves. Experiments at higher magnetic fields with improved antennas which can excite amore desirable wave polarization are planned in 2011.

Plasma transport is governed by microscopic turbulence. In order to measure the electron temperaturefluctuation using electrostatic probes, the fast voltage sweeping technique was developed. The validity ofthe current-voltage characteristic curve was confirmed. The fitting errors in the evaluation of the electrontemperature itself are less than 10% of fluctuation levels in the electron temperature. In order to improvethe signal-to-noise ratio in low density plasmas, and to measure the electron pressure anisotropy andthe electron current density, a multi-pass Thomson scattering system is being developed. As a proof-of-principle, a double-pass Thomson scattering system is being tested. The electron pressure parallel to themagnetic field (pe‖), electron pressure perpendicular to the magnetic field (pe⊥), and electron current density

(je) at magnetic axis can be measured. This system should be able to measure temperature anisotropies ofover 15% (Te‖/Te⊥ > 15%) in high density (ne > 3× 1018 m−3) plasmas. A high time resolution electrontemperature and density measurement using helium line intensity ratios based on the collisional-radiativemodel is being developted. The intensity ratio can be calculated using Collisional-Radiative model. A24-channel system (8 spatial channels at three wavelengths) is in use. Initial results indicate that bothelectron temperature and density have profiles peaked on the outboard side.

Member: Kimio TSUBONO and Yoich ASO

The detection of gravitational waves is expected to open a new window into the universe and brings us anew type of information about catastrophic events such as supernovae or coalescing binary neutron stars;these information can not be obtained by other means such as optics, radio-waves or X-ray. Worldwideefforts are being continued in order to construct detectors with sufficient sensitivity to catch possiblegravitational waves.

In 2010, a new science project, LCGT (Large-scale Cryogenic Gravitational wave Telescope)was approvedand funded by the Leading-edge Research Infrastructure Program of the Japanese government. This un-derground telescope is expected to catch gravitational waves from the coalescence of neutron-star binariesat the distance of 200Mpc.

A space laser interferometer, DECIGO, was proposed through the study of the gravitational wave sourceswith cosmological origin. DECIGO could detect primordial gravitational waves from the early Universe atthe inflation era.

Research Subjects: Submillimeter-wave and Terahertz Astronomy, Star and Planet For-

mation, Chemical Evolution of Interstellar Molecular Clouds, Development of

Terahertz Detectors

Member: Satoshi Yamamoto and Nami Sakai

Molecular clouds are birthplaces of new stars and planetary systems, which are being studied extensively

as an important target of astronomy and astrophysics. Although the main constituent of molecular clouds

is a hydrogen molecule, various atoms and molecules also exist as minor components. The chemical compo-

sition of these minor species reflects formation and evolution of molecular clouds as well as star formation

processes. It therefore tells us how each star has been formed. We are studying star formation processes

from such a astrochemical viewpoint.

Since the temperature of a molecular cloud is as low as 10 K, an only way to explore its physical structure

and chemical composition is to observe the radio wave emitted from atoms, molecules, and dust particles.

In particular, there exist a number of atomic and molecular lines in the millimeter to terahertz region, and

we are observing them with various large radio telescopes in the world.

We are conducting a line survey of low-mass star forming regions with Nobeyama 45 m telescope and

ASTE 10 m telescope, aiming at detailed understanding of chemical evolution from protostellar disks to

protoplanetary disks. In the course of this effort, we have recently established a new chemistry occurring

in the vicinity of a newly born star, which is called Warm Carbon Chain Chemistry (WCCC). In WCCC,

251

27. SAKAI (HIROFUMI) GROUP

carbon-chain molecules are produced by gas phase reactions of CH4 which is evaporated from ice mantles.

This has recently been confirmed by our detection of CH3D in one of the WCCC sources, L1527. Existence

of WCCC clearly indicates a chemical diversity of low-mass star forming regions, which would probably

reflect a variety of star formation. We are now studying how such chemical diversity is brought into the

protoplanetary disks.

In parallel to such observational studies, we are developing a hot electron bolometer mixer (HEB mixer)

for the future terahertz astronomy. We are fabricating the phonon cooled HEB mixer using NbTiN and NbN

in our laboratory. Our NbTiN mixer shows the noise temperature of 570 K at 1.5 THz, which is the best

performance at this frequency in spite of the use of the wave-guide mount. Furthermore, we successfully

realized the waveguide-type NbN HEB mixer by using the NbN/AlN film deposited on the quartz wafer.

The 0.8/1.5 THz dual-band HEB mixer receiver is now being assembled, which will be installed on the

ASTE 10 m telescope for astronomical observations in 2011.

Research Subjects: Experimental studies of atomic, molecular, and optical physics

Member: Hirofumi Sakai and Shinichirou Minemoto

Our research interests are as follows: (1) Manipulation of neutral molecules based on the interaction

between a strong nonresonant laser field and induced dipole moments of the molecules. (2) High-intensity

laser physics typified by high-order nonlinear processes (ex. multiphoton ionization and high-order harmonic

generation). (3) Ultrafast phenomena in atoms and molecules in the attosecond time scale. (4) Controlling

quantum processes in atoms and molecules using shaped ultrafast laser fields. A part of our recent research

activities is as follows:

(1) All-optical molecular orientation [1]

We report clear evidence of all-optical orientation of carbonyl sulfide molecules with an intense nonreso-

nant two-color laser field in the adiabatic regime. The technique relies on the combined effects of anisotropic

hyperpolarizability interaction and anisotropic polarizability interaction and does not rely on the perma-

nent dipole interaction with an electrostatic field. It is demonstrated that the molecular orientation can be

controlled simply by changing the relative phase between the two wavelength fields. The present technique

brings researchers a new steering tool of gaseous molecules and will be quite useful in various fields such

as electronic stereodynamics in molecules and ultrafast molecular imaging.

(2) Dependence of the generation efficiency of high-order sum and difference frequencies in

the extreme ultraviolet region on the wavelength of an added tunable laser field [2]

252

28. GONOKAMI GROUP

We investigate the dependence of the generation efficiency of sum and difference frequencies in the

extreme ultraviolet (xuv) region on the wavelength of an added tunable laser field. The wavelength of the

added field ranges from 600 nm to 1500 nm. The generation efficiency of sum and difference frequencies is

dramatically enhanced when the wavelength of the added field is longer than that of the fundamental field

for pure harmonics. The discussions are held to the added field with perturbative intensity first, and they

are further extended to that with nonpertubative intensity.

(3) Effect of nuclear motion observed in high-order harmonic generation from D2/H2 molecules

with intense multi-cycle 1300 nm and 800 nm pulses [3]

We investigate high-order harmonic generation from D2/H2 molecules with intense multi-cycle pulses

centred both at 1300 nm (60 fs) and at 800 nm (50 fs) together with that from N2/Ar as a reference. The

experimental observations with 1300 nm pulses are different from those with 800 nm pulses both in spectral

shapes and in intensity ratios ID2/IH2 . The effect of nuclear motion in D2 and H2 is more distinctive for

1300 nm pulses than for 800 nm pulses. With multi-cycle pulses of 50–60 fs, the intensity ratios ID2/IH2

are found to be higher for both 800 nm and 1300 nm pulses than those with few-cycle pulses of 8 fs, which

is attributed partly to the contribution of the coupling between the 1sσg and 2pσu states in D+2 and H+

Member:Makoto Gonokami, Kosuke Yoshioka

Our new research activities have started within the Department of Physics. We are trying to explore

new aspects of many-body quantum systems and their exotic quantum optical effects through designed

light-matter interactions. Our current target consists of a wide variety of matter, including excitons and

electron-hole ensemble in semiconductors, antiferromagnetic magnons and ultracold atomic gases. In par-

ticular, we have been investigating the Bose-Einstein condensation phase of excitons, which is considered

the ground state of electron-hole ensemble but as yet not proven experimentally. Based on quantitative

spectroscopic measurements, the temperature and density are determined for an exciton gas in a quasi-

equilibrium condition trapped inside a high purity crystal kept below 1 K.We also investigate novel optical

and terahertz-wave responses for some artificial nanostructures obtained by advanced micro-fabrication

technologies. As the Director of the Photon Science Center, within the Graduate School of Engineering, a

project was started to develop new coherent light sources; covering a broad frequency range from terahertz

Research was established. This is one of the Advanced Research Foundation initiatives from the Ministry

of Education, Culture, Sports, Science and Technology. Within this initiative, we are developing intense

and stable coherent light sources at a high repetition rate (That facility is named ”Photon Ring”).

Research Subjects:Molecular Mechanism of Neural Network Formation

Member:Akinao Nose, Hiroshi Kohsaka and Etsuko Takasu

254

29. NOSE GROUP

What is the physical basis of formation of the brain? The aim of our laboratory is to elucidate the

molecular mechanism of neural development and function by using, as a model, the simple nervous system

of the fruitfly, Drosophila. We focus on the synapses between motor neurons and their target muscles, and

study the molecular mechanisms of how specific synaptic partners recognize each other and form synaptic

connections. The following research plans are in progress.

1. Molecular mechanism of the neuromuscular target recognition

The proper functioning of the nervous system depends on precise interconnections of distinct types of

neurons. Therefore, understanding how neurons specifically find and recognize their target cells is a central

question in neuroscience. We have identified specific recognition molecules that are expressed in specific

target cells and determine synaptic specificity.

1.1. Neural wiring by a negative signal: identification of a repulsive target cue that determines

synaptic specificity.

The final matching of pre- and postsynaptic cells is thought to be mediated by specific molecular cues

expressed on the target cells. While previous studies demonstrated essential roles of several target-derived

attractive cues, less is known about the role of repulsion by non-target cells. In collaboration with Prof.

Hiroyuki Aburatani (Research Center of Advanced Science and Technology, University of Tokyo), we con-

ducted single-cell microarray analysis of two neighboring muscles (called M12 and M13) in Drosophila,

which are innervated by distinct motor neurons, by directly isolating them from dissected embryos. We

identified a number of potential target cues that are differentially expressed between the two muscles,

including M13-enriched Wnt4, a secreted protein of the Wnt family. When the function of Wnt4 was

inhibited, motor neurons that normally connect with M12 formed smaller synapses on M12 but instead,

inappropriately connected with M13. Conversely, forced expression of Wnt4 in M12 inhibited synapse for-

mation by these motor neurons. These results suggest that Wnt4 generates target specificity by preventing

synapse formation on a non-target muscle.

2. Live-imaging of synapse formation in vivo

Synapses are specialized junctions through which neurons signal to each other and to other target cells

such as muscles and are crucial to the functioning of the nervous system. However, the mechanism of how

the synapses form during development remains poorly understood. We applied live imaging of fluorescent

fusion proteins expressed in the target cells to visualize the process of synapse formation in developing

embryos.

2.1 Bidirectional recognition for neuronal matchmaking

The mechanism of how specific neural connections are formed in living animals is one of the significant

topics in neuroscience. A traditional view is one-sided: motile growth cones of the presynaptic neurons

actively search for the target cell, whereas the target cells wait still to be selected by adequate partner

255

30. HIGUCHI GROUP

neurons. We found that not only presynaptic neurons but also postsynaptic target cells actively search for

their partners during the formation of neural network. Such bidirectional recognition might be critical for

the development of precise neural connections not only in Drosophila but also in other animals including

humans.

30 Higuchi Group

Research Subjects: Motor proteins in in vitro, cells and mice

Member: Hideo Higuchi and Motoshi Kaya

We succeeded in measuring stiffness and step size of single-few myosin molecules at in vitro system and

imaging the dynamics of GFP-EB1 molecules in mice, that is, in vivo. The detail are as following. Skeletal

muscles are necessary not only for body segment movements, but also for our daily communications, such as

speaking, writing and facial expressions. Skeletal myosins are an essential protein that interacts with actin

filaments and generates forces by stretching the elastic portion of myosin heads during muscle contractions.

It has been well known that the mechanical efficiency of muscle contraction can be up to 50 %, which is

much higher than that of 15 % in automobile or of 1 % in micro-machines. Theoretically, the contribution

of friction to the energy loss is more pronounced as the body size decreases. Thus, our question is why

a nano-scale protein, skeletal myosin, can achieve such a high mechanical efficiency? In order to address

this question, we measured the elasticity of single myosin molecules and the displacements generated by

myosins by the combination of optical trapping and fluorescence imaging techniques with a few nanometer

and pico-newton accuracy. We found that myosins become extremely stiff when they are stretched during

the force generation period, while they becomes much more complaint when they are compressed after the

force generation. In the presence of ATP, myosins generate the sliding movement of actin filament by 8

nm. The biphasic elastic response implies that single skeletal myosins are optimally designed to generate

the contractile force efficiently by enhancing the ability of the force generation before the force generation

while minimizing the resistance force after the force generation. Microtubles (MTs) are highly dynamic

and polar structures that are involved in many important cellular processes including mitosis, migration,

adhesion, cargo trafficking, in addition to tumor metastasis. Endbinding protein 1 (EB1) is a MT plus-

end binding proteins that are specifically accumulated at the polymerizing end of MTs. In this study, we

imaged GFP-EB1 to observed the real-time MT dynamics in living cells and mice. Using a spinning disc

confocal microscopy the comet-like localizations of GFP-EB1 were observed in human breast cancer cell

line. We analyzed the velocity of GFP-EB1 comets, indicating MT growing speed with the nanometer scale,

by tracking the comet centers using an automated computer program. It was faster around centrosome

in the central region of the cell than submembrane region. We also imaged successfully GFP-EB1 in

three-dimensionally cultured cells in the extracellular matrix that mimics the three-dimensional structure

of living tissue. To determine MT dynamics in living mice, breast cancer cells expressed GFP-EB1 were

xenografted in nude mice. GFP-EB1 comets were observed under the confocal microscopy in vivo. These

techniques have potential to enable quantitative analysis of MT dynamics in living mice, for example, under

the presence of anticancer reagents.

Simone De Liberato

Dr. Simone De Liberato theoretically studied the physics of intersubband transitions in two dimensional

electron gases in presence of an electromagnetic field resonant with the transition. The system is thus in the

so-called ultrastrong coupling regime and the intersubband polaritons are observable. Simone De Liberato

also studied the dynamical Casimir effect and he modeled quantum transport and electroluminescence in

such semiconductor structures. His work has both a fundamental and an applied aspect, in fact his results

can be applied in the field of quantum cascade lasers in the THz range.
