PULLMAN, Wash.—Researchers atWashington State University haveused a super-cold cloud of atomsthat behaves like a single atom to seea phenomenon predicted 60 yearsago and witnessed only once since.

The phenomenon takes place in theseemingly otherworldly realm ofquantum physics and opens a newexperimental path to potentiallypowerful quantum computing.

Working out of a lab in WSU’sWebster Hall, physicist PeterEngels and his colleagues cooledabout one million atoms ofrubidium to 100 billionths of adegree above absolute zero. Therewas no colder place in the universe,said Engels, unless someone wasdoing a similar experimentelsewhere on Earth or on anotherplanet.

At that point, the cluster of atomsformed a Bose-Einstein condensate– a rare physical state predicted byAlbert Einstein and Indian theoristSatyendra Nath Bose – afterundergoing a phase change similarto a gas becoming a liquid or a liquidbecoming a solid. Once the atomsacted in unison, they could beinduced to exhibit coherent“superradiant” behavior predictedby Princeton University physicist

involving coupling to photon fields.Because the coupling of atoms andphotons is usually very weak, theirbehavior was extremely hard toobserve, he said.

“What our colleague ChuanweiZhang realized is, if you replacedthe light with the motion of theparticles, you got exactly the samephysics,” said Engels. Moreover, it’seasier to observe. So while theircloud of atoms measures less thanhalf a millimeter across, it is largeenough to be photographed andmeasured. This gives experimentersa key tool for testing assumptionsand changes in the atomic realm of

quantum physics.

“We have found animplementation of thesystem that allows us togo in the lab and actuallytest the predictions of theDicke model, and someextensions of it as well, ina system that is not nearlyas complicated as peoplealways thought it has to befor the Dicke physics,”Engels said.

“This large group of atoms does notbehave like a bunch of balls in abucket,” said Engels. “It behaves asone big super-atom. Therefore itmagnifies the effects of quantummechanics.”

Engels’ findings appear in thejournal Nature Communications. Co-author and collaborator ChuanweiZhang, a former WSU physicistnow at the University of Texas atDallas, led the theoretical aspects ofthe work.

Ph.D. and M.S. programs in the Department ofPhysics & Astronomy

The Department of Physics and Astronomy at WashingtonState University is built around a small but highlyproductive faculty whose research expertise providesstudents a wide variety of research experiences. The highlyrigorous undergraduate program prepares graduates to becompetitive in top graduate programs or for employment.The Ph.D. program and the thesis master's degree blenddemanding coursework with cutting-edge research toprepare graduates for jobs in academia, industry, andgovernment labs. Our programs emphasize core academiccompetency and research excellence.

Physics is the study of the material world. Its historicalmission was to push the boundaries of superlatives: thesmallest subatomic particle, the quickest time interval, themost precise measurement, the most perplexing ofunexplained phenomena. In the 21st century, thesechallenges are augmented with a need to understand howparticles interact under extreme conditions or complexsituations. Astronomy is the study of the universe from thesize scales of planets to the ultimate size scale of all. Itencompasses the risks of meteor impacts, the intricateballet of planetary systems, and the warping of spacetimenear a black hole.

The WSU Department of Physics and Astronomyaims to prepare young scientists for careers in theseand related areas. We offer bachelor's, master's, anddoctoral degrees for students that aspire to thechallenge of pushing the frontiers of humanknowledge.

Fall 2015 priority deadline:January 10, 2015.

We accept applications afterthis date but they are notconsidered priority;admissions considerationsbegin in February 2015.

This concurrent duality can be exploited by quantum computing.So where a conventional computer uses 1s and 0s to makecalculations, the fundamental units of a quantum computer couldbe 1s and 0s at the same time. As Wired magazine(http://www.wired.com/2014/05/quantum-computing/#x)recently noted, “It’s a mind-bending, late-night-in-the-dorm-room concept that lets a quantum computer calculate atridiculously fast speeds.”

PULLMAN, Wash. – The Washington State University flaghas flown in many places around the world – from ESPNGame Day to the Great Wall of China – and now morethan 18 miles into the stratosphere.

A Cougar flag attached to a weather balloon recentlylaunched from the center of the Pullman campus reachednearly 100,000 feet. The flight was part of a WSU Physicsand Astronomy Club student project; now the flag is up forauction (see http://www.ebay.com/itm/Phyiscs-Astronomy-Club-WSU-Flag-Post-Flight-/251531402832?).

Launched from the roof of the Terrell Library during WSUMom’s Weekend in April, the balloon was projected toreach an altitude between 40,000 and 60,000 feet, saidNicholas Cerruti, senior physics instructor and clubfaculty advisor. The team was surprised by the altitude datafrom the internal monitor of the recovered balloon.

Jesse Miller, club president and a recent 2014 physicsgraduate, said team members initially thought there was aglitch in the data.

“I was kind of dubious at first because there was datarecorded for the first half hour, and then it cut out for areally long time,” he said. “Then there is 15 minutes of dataclustered right around the peak.”

That peak, said Eric Beier, club treasurer and a junior inphysics, was officially 98,093 feet above Earth. That altitudeis believed to be second only to that of a Cougar flag thataccompanied WSU alumnus John Fabian, ’62, on the SpaceShuttle Discovery in 1985.

The balloon’s predicted flight path, based on jet streammapping software, set the landing site on the Clearwater

Chad Garrison, flight commanderand physics major, said the goal ofthe project was to design a high-altitude physics experiment platformthat could be repeated by futureclub members. The flag launch, hesaid, allowed for “alpha testing ofthe apparatus, making a live launchto understand the physics anddetermine procedures for futureexperiments.”

The club hopes the balloon launchwill become an annual event, muchlike their popular fall Dad’s Weekendpumpkin drop from the 12th floorof Webster Hall.

The flag auction is open until noonSaturday, May 24. Proceeds willbenefit the WSU Physics andAstronomy Club.

Plateau, about a 90-minute drivesoutheast of Pullman. The jetstream shifts slightly every day, sothe launch needed to be carefullytimed to avoid pushing the balloontoo far south or east; if the balloondescended into Hell’s Canyon orlanded in Idaho’s vast stretches offorest, recovery would be difficult.

The balloon kit purchased by theclub included a GPS unit to track itstrajectory. As the balloon and flagrose into the sky after the launch,club members watched the signalhead east over Idaho.

Even with the higher altitude, theballoon did land in the predictedregion of the plateau. The recoveryteam easily retrieved it from afarmer’s field near Nez Perce, Idaho.

A GoPro camera fitted to theapparatus captured the flag’s ascent.The two-hour footage shows therolling hills of the Palouse quicklygiving way to white clouds scatteredacross the sky. Thirteen minutes intothe flight, the balloon encounters ahailstorm, but four minutes later thesky is clear and blue.

At the balloon’s high point, the sunand blackness of space are visibleabove the curve of the Earth as theflag flutters at the bottom of thescreen.

Why the balloon went so highremains a mystery. Weather balloonsare designed to self-deflate andreturn to Earth: as a balloon rises,the surrounding air pressurebecomes lower; higher pressureinside means the balloon expandsuntil it leaks or pops.

The altitude a balloon reachesdepends upon how much helium isin it. “More helium would have alower maximum altitude, since thepressure inside the balloon would begreater and the balloon would popsooner,” said Cerruti. If the balloonhas less helium, it should rise moreslowly but stay aloft longer.

Superfluids, quantum physics,and coffee: An interview withMichael McNeil Forbes

STORY Sabrina Zearott, staff writer

Introducing one of the newest members of theDepartment of Physics & Astronomy.

WHEN Michael McNeil Forbestalks about his research, it’s easy tosee why he works withsupercomputers.

During my interview with him, Irecall that for most of mychildhood, I wanted to be anastronomer. I read Astronomymagazine, tried semi-successfully tooperate second-hand telescopes, andstruggled through a Harvardastronomy course out of interest.Talking to Forbes, however, is likereading an entire textbook onquantum mechanics in an hour.

“Am I overwhelming you?” he asks.“Yes,” I admit, “but keep going, thisis fascinating.”

A new assistant professor in WSU’sDepartment of Physics &Astronomy, Forbes is a native ofCalgary, Alberta, Canada. Aftergetting involved in the PhysicsOlympiad (he placed first in Canadaand 31st in the world), he went tothe University of British Columbiato earn an honors degree incomputer science and physics,followed by an M.Sc. in physics,then headed to MIT to earn a Ph.D.Most recently, he was a researchassistant professor and fellow at theUniversity of Washington’s Institutefor Nuclear Theory (INT).

Some of Forbes’ early researchfocused on the early universe and aparadox that has yet to be resolved:baryogenesis, or the formation ofmatter. The standard model ofparticle physics assumes a certaindegree of symmetry, known ascharge-parity, or CP. Violations ofCP are rare and very small - that is,there’s not a lot of observableasymmetry when it comes to particleinteractions. Yet if everything issymmetrical, there should beroughly equal amounts of matterand antimatter in the universe, andthey should annihilate each otherand leave only light.

Mathematically speaking, theformula used to describe QCD(quantumchromodynamics, orparticle interactions)contains a term that,at its “natural”value, can result inCP violation. Atsome point in theuniverse’s history,that term’s valuechanged to 0,meaning essentiallyno CP violation (orantimatter). According to Forbes,something must have happened inthe early universe to leave us withalmost no antimatter; he wants tofind out what, and to find out where

the missing antimatter is.

Ariel Zhitnitsky, Forbes’ M.Sc.advisor at UBC, proposed that theearly universe contained “domainwalls” that separated matter andantimatter, then sealed antimatteroff into bubbles. These bubbles, or“quark nuggets,” are thought to existtoday as dense grain-of-sand-sizedpieces of dark matter that weigh asmuch as a truck. The change in theQCD formula’s term was explainedby MIT’s Frank Wilczek, laterForbes’ Ph.D. advisor and the 2004winner of the Nobel Prize, whostated that the term could beeliminated using a dynamical “axionfield” – as the universe cools, theterm vanishes. Zhitnitsky and

Forbes’ argument isthat knots in this field(domain walls)provide the CPviolation necessary toseparate antimatterfrom matter and trapthe former, restoringCP symmetry.

This theory is hard totest, as dark matter isnot easily observable.

However, Forbes and colleagueshave been able to observe lightemissions that are consistent withpredicted dark-matter annihilation at

The research thatbrought Forbes toWSU is a little

different, and it’swhere the

supercomputerscome in.

The research that brought Forbes toWSU is a little different, and it’swhere the supercomputers come in.At MIT, he became interested inhigh-density particle interactions(QCD, or quantumchromodynamics) – specifically,what happens in the interiors ofneutron stars. These stars spin liketops, eventually slowing down asthey lose momentum; occasionally,they “glitch” and speed up again,and physicists have been trying tounderstand why. This is verydifficult to replicate in a lab, ofcourse, and requires the world’sbiggest supercomputers to simulate.However, Forbes tells me thatneutron stars behave very similarlyto cold atoms. This means that hecan compare computer simulationsto cold-atom experiments and thenbuild models based on the latter,bypassing the need for theenormous calculations and energyrequirements of simulating nuclearreactions in a lab. WSU had exactlythe combination of theoretical andexperimental work (Doerte Blumeand Peter Engels, respectively) thatForbes needed.

Our discussion isn’t all quantumphysics. The conversation toucheson other things as well: his collegeyears, his hobbies, his love of high-quality coffee. When he first visitedthe world-renowned MIT campus,he approached it from the“industrial area” to the south, thatgrungy urban zone located betweenHarvard and MIT; it didn’t makehim very enthusiastic aboutattending, he tells me as I laugh. Wetalk about coffee - I consider myselfa coffee fan, but it quickly becomesclear that he knows significantlymore than I do about, well, almosteverything related to it. (He brings

me a bean later so I can see whathe’s talking about.) He’s an avidcycler and skier as well, and isinterested in the science of sound.

Finally, Forbes loves to teach. Aparticular favorite of his was theScience One course at UBC, whichcombined math, physics, biology,and chemistry in a single course; hetells me that students learned toanswer “why” questions, and learnedthe requisite math for each scienceproblem they tackled, an innovativeapproach that resulted in significantprogress over a year. AlthoughWSU’s undergraduate courses aremuch larger than Science One,Forbes hopes to carry over some ofScience One’s principles and applythem here once he begins teaching.

In the meantime, he has research todo.

PULLMAN, Wash. – Quite byaccident, Washington StateUniversity researchers have achieveda 400-fold increase in the electricalconductivity of a crystal simply byexposing it to light. The effect,which lasted for days after the lightwas turned off, could dramaticallyimprove the performance of deviceslike computer chips.

WSU doctoral student MarianneTarun chanced upon the discoverywhen she noticed that theconductivity of some strontiumtitanate shot up after it was left outone day. At first, she and her fellowresearchers thought the sample wascontaminated, but a series ofexperiments showed the effect wasfrom light.

“It came by accident,” said Tarun.“It’s not something we expected.That makes it very exciting toshare.”

The phenomenon they witnessed —“persistent photoconductivity” — isa far cry from superconductivity, thecomplete lack of electrical resistancepursued by other physicists, usuallyusing temperatures near absolutezero. But the fact that they’veachieved this at room temperaturemakes the phenomenon moreimmediately practical.

And while other researchers havecreated persistent photoconductivityin other materials, this is the mostdramatic display of thephenomenon.

The research, which was funded bythe National Science Foundation,appears this month in the journalPhysical Review Letters.

“The discovery of this effect atroom temperature opens up newpossibilities for practical devices,”said Matthew McCluskey, co-author of the paper and chair ofWSU’s physics department. “Instandard computer memory,information is stored on the surfaceof a computer chip or hard drive. Adevice using persistentphotoconductivity, however, couldstore information throughout theentire volume of a crystal.”

This approach, called holographicmemory, “could lead to hugeincreases in information capacity,”McCluskey said.

Strontium titanate and other oxides,which contain oxygen and two ormore other elements, often display adizzying variety of electronicphenomena, from the highresistance used for insulation tosuperconductivity’s lack of

resistance.

“These diverse properties provide afascinating playground for scientistsbut applications so far have beenlimited,” said McCluskey.

McCluskey, Tarun and physicistFarida Selim, now at BowlingGreen State University, exposed asample of strontium titanate to lightfor 10 minutes. Its improvedconductivity lasted for days. Theytheorize that the light frees electronsin the material, letting it carry morecurrent.

The DepartmentWelcomes AssistantProfessor Brian CollinsSTORY Sabrina Zearott PHOTOS Brian Collins

Brian Collins, assistant professor in theDepartment of Physics & Astronomy, comes toWashington State University from the NationalInstitute of Standards and Technology (NIST) inMaryland, where he was a National ResearchCouncil Fellow and conducted research at theAdvanced Light Source (ALS) in Berkeley,California.

Collins’ planned research at WSU includesinvestigating resonant x-ray/soft-matterinteractions to develop microscopy and scatteringtechniques. Soft matter absorption of x-rays altersthe materials' optical properties in specific waysthat are unique to each type of bond and molecule- what Collins calls a “resonant signature.” Thissignature can be used to improve microscopy andscattering techniques by allowing improvedcontrast and identification of observed structures.Collins hopes to apply these improved techniquesto “optoelectronically active polymers and smallmolecules for use in organic devices such as lightemitting diodes, solar cells, transistors andbatteries,” which could ultimately be printed ontoflexible materials. Such organic devices couldrepresent major advances in technology andenergy. First, however, Collins plans to focus onmeasuring, characterizing, and understanding boththe structures that are formed and theoptoelectronic processes in these devices, all ofwhich could have important implications in thefield. This research is an extension of hispostdoctoral work at NIST.

Collins earned his Ph.D. and M.S. from theUniversity of North Carolina, where he carriedout research on epitaxial films at the AdvancedPhoton Source at Argonne National Laboratory;he earned his B.A. from Gustavus AdolphusCollege in Minnesota. He is a member of both theMaterials Research Society and the AmericanPhysical Society (APS), as well as the ALS UserExecutive Committee’s first postdoctoral member.He has a wife and three daughters; hobbiesinclude reading and watching sciencefiction/fantasy, pursuing outdoor activities such ascamping and hiking, and playing the piano andsinging.

In a high school math classroom inLos Angeles, pairs of students make shapes using wire,pliers, and instructions written on a software programcalled Turtle. It isn’t easy: partner one has to think aboutthe outlines of the shape, then use the software to tell ananimated turtle where to go (“walk two inches, turn right,walk three inches…”). The resulting path potentially takesplace in three dimensions.

By relaying the path’s instructions to the other student,the first student can explain how to turn a wire into ashape. If the pair gets it right, partner two’s masterpieceshould resemble partner one’s original vision. Ifnot…they need to recalculate.

What sounds like a fun math project is part of a newcurriculum and science initiative, funded through the $2million National Science Foundation grant recentlyawarded to Mark Kuzyk.

Mathematics), the main purpose of the grant is to usethese concepts to develop the relatively new science ofmorphing “smart” materials. The first step to this goal isresearch on neurological disease treatment using“intelligent optical fibers,” per the National Academy ofSciences’ 2013 “Grand Challenge”: at WSU, Kuzyk andhis graduate students are developing optical fibers that canbe manipulated, Turtle-path style, inside the human brain.

Kuzyk’s group, which includes graduate studentsElizabeth Bernhardt, Nathan Rasmussen, and JosephLanska, is working to design a better “deep brainstimulation device.” Deep brain stimulation – in which athin electrode is inserted into a specific area of the brain –has been shown to help patients suffering fromneurological conditions from Parkinson’s to Alzheimer’s.

Such technology could be adapted for a number of uses –Kuzyk mentions that astronauts, isolated for months,could be implanted with a device that could be remotelystimulated to help prevent depression. However, thecurrent electrode design is not able to be manipulatedonce inside the brain, so the surgeon has to be incrediblyprecise to avoid having to re-insert the device.

The new optic fiber technique being developed at WSU isbased on the idea that the fiber can bend as needed bysending light through it at specific wavelengths – in otherwords, it could be manipulated once placed inside thebrain. The research is being undertaken in partnershipwith Dr. Andres Lozano, who gave a recent TED Talk onbrain stimulation; it is also being carried out incollaboration with Caltech (material synthesis/outreach)and both UMass Amherst and Kent State University(materials development and characterization).

At the moment, the goal is to perfect the fibers, whichconsist of three gold (hypoallergenic, non-rusting) wiresdrawn down through melted Poly(methyl methacrylate), aplastic also known as PMMA. Kuzyk hopes to finish this

by the end of this year. Ultimately, possibly many years from now, the hope is that these fibers can be used to make“smart fabrics” that contain devices that, Kuzyk says, can “talk to each other with light” and “change shape locally.”

That’s where the art-science collaboration comes back into play: Kuzyk is working with wire artist Elizabeth Berrienand origami specialist Robert Lang to understand wire-shape construction in greater depth. Regarding smart materials,fibers (and cloth) could be locked into particular shapes, only to be unlocked as needed; they could change in responseto temperatures or other stimuli. Such technology and techniques could have vast implications, from materials scienceto the military; in the meantime, Kuzyk’s work is broadening horizons in medicine...and U.S. science curricula.

The WSU Planetarium (located in Sloan Hall 231) hosted several shows this spring, ranging from Stargazing 101 tomore complex “journeys” meant to help the audience understand the seasons and what might be out there in the largergalaxy. Most of the shows were presented by Kaylan Petrie, a mathematics and science education doctoral student atWSU who has done similar presentations elsewhere. Guy Worthey described the aim of the shows as “Connectingpeople to their world. People have a hunger to know their universe, and modern society has paradoxically distanced usfrom many things that people experienced before the invention of the light bulb.” “Stargazers” received star charts forStargazing 101 - Worthey said it was gratifying to “see students’ eyes light up” as they figured out how to make themwork.

Worthey has been working with the planetarium since 2001 along with Michael Allen. Approximately 25,000schoolchildren have visited in that time, Worthey said. The planetarium anticipates adding a low-fidelity digitalprojection system built here at WSU to give attendees a sense of “the benefits that a professional projector couldbring” - donations are welcome at http://secure.wsu.edu/give/.

It was the height of World War II when afarmer south of the Snake River spottedsomething unusual.

Even today, the area is quite remote - mostly flat and semi-arid, itsdusty fields stretch to the horizon, punctuated by the occasionalroad. It remains relatively uninhabited even in 2014 - the tiny townof Anatone, along the highway that runs from the Lewis-ClarkValley down to Oregon, boasts a population in the double digits.The farmer, then, had reason to be suspicious of a new-looking,windowless van (in an era of rationing, no less) with what appearedto be an antenna on top. The van stopped and men got out, thenwent about setting up what looked like radio equipment of somekind.

Not long afterward, the farmer showed up with the sheriff anddemanded to know what the men were doing.

The men, likely startled at being caught in such a remote area, didn’tquite answer the sheriff ’s questions. All they said was that they wereworking on something top secret to do with the war effort. Finally,the increasingly suspicious sheriff managed to get a phone numberfrom them; he called the number and, sufficiently satisfied with whathe heard from the person on the other end, finally left.

The men were neither exceptionally clumsy foreign spies nor traitors.They were in fact physicists from the nearby State College ofWashington, also called WSC, and they were indeed working on asecret government project: improving the radar detection process. Inthis case, the men were trying to line up their transmitters with Mt.Spokane and Steptoe Butte and had driven into the fields to get adirect line. Their project was essential to the government: in June1942, 1800 Japanese soldiers had landed in the Aleutian Islands, butthe U.S. radar readings were so affected by atmospheric conditionsthat the resulting U.S. bombing raid was carried out over the ocean,far from the actual location. Clearly, something needed to be done.

The U.S. government’s Office of Scientific Research andDevelopment (OSRD) focused on trying to understand radardistances and what is known as the “radar horizon” - the distancebeyond past which radar cannot “see.” In early 1942, according tolongtime beloved physics instructor Alfred “Al” Butler (M.A. 1944,Anderson), both Paul Anderson (chair 1931-1961) and S. T.Stephenson were recruited by the Radiation Laboratory at theMassachusetts Institute of Technology (MIT), where they worked on

said in later recollections; he wrote that “[n]one of ushardly saw them and we certainly didn’t know whatthey were working on.” This level of secrecy was notunusual. In one instance, the dean of the WSCGraduate School had noticed an apparentlyinnocuous pattern of address changes published in ajournal: rare-earth element specialists and otherchemists were relocating en masse to the cities ofHanford and Richland, Washington. Upon pointingout to the journal that the American Chemical Societymight want to establish a chapter in one of thoseplaces, he was visited by the FBI, who wanted toknow just what he meant by his idea. (As is nowwidely known, Hanford and Richland were the sitesof top-secret research on atomic weapons. Thejournal stopped publishing address changes

immediately lest similar patterns be discovered byenemy agents.) Another faculty member, ClarenceZener, did classified work for the Watertown Arsenalin Watertown, Massachusetts - likely related to armor-piercing projectiles - and was later director ofresearch at Westinghouse - Butler recalled that henever did find out exactly what Zener was workingon.

In 1943, the radar research paid off and WSC wonthe contract against larger institutions (such as MIT)to build the Navy’s radar-range-detecting equipment,which was tested in the Pacific and adopted by the AirForce, the Navy, and the militaries of Britain,Australia, and New Zealand. Anderson ended upworking in Washington, D.C., as part of GeneralMacArthur’s newly-founded Office of Field Service,to put the research into “operational use in theSouthwest Pacific,” according to Butler. The otherresearchers collaborated with the Australian radar-research group out of the University of Sydney.Eventually the work was extended to assist indetecting low-flying aircraft. Anderson and

the Ground Control Approach system used to helpaircraft land in low-visibility conditions. After theJune invasion, however, atmospheric conditions andtheir effects on radar became an essential topic ofresearch. Anderson and Stephenson suggested thatthe work be carried out at WSC; they were outfittedwith the van mentioned above, which contained an X-band (3 cm) receiver, portable X-band transmitter,and radar dishes that could be attached to the roof.They recruited both Kenneth Fitzsimmons (M.S.1931, Anderson), machinist and physics staffmember, and civil engineer Charles Barker(professor and radio ham) from WSC to help them.

Their project involved setting up transmitter stationson Mt. Spokane, Steptoe Butte, and the hills south of

the Snake River in order to transmit microwave beamsover distances of 50 and 110 miles while being closeenough to the ground to monitor atmosphericconditions. Despite their top-of-the-line equipment,working out in rural Washington was not easy: in the1940s, there were few plowed roads in the winter, sothey often had to do this by snowshoe or hiking.Another set of testing at Flathead Lake, Montana,involved using a bow and arrow to shoot a fishing lineover a tree limb and attach recording instruments tomeasure atmospheric conditions at 40 feet above thelake. (The archery equipment was borrowed from alocal resident, who was likely very confused.)

The group did have a bit of fun despite thedifficulties of the work: they had two radio sets, oneof which ran on a frequency only they could access,so listeners elsewhere could only hear half theconversation, and the group put that knowledge toentertaining use at times.

Anderson and co.’s work was so secret that theycouldn’t even mention the word “radar,” as Butler

Stephenson had war adventures of their own:Anderson helped brief Air Force officers as part ofan invasion on an island in the Gulf of Leyte (thePhilippines), while Stephenson had to dive into abunker to avoid enemy aircraft strafing an airport.

WSC’s importance to the war effort, which includedtraining Army & Air Force (AAF) cadets, wasimpressive considering its isolation and the fact thatthe physics department had not officially existedbefore 1919. Before that, physics was taught as partof engineering, beginning with Professor AddisonR. Saunders in 1894 (it remained part of the Collegeof Engineering for over 50 years). The first laboratoryat the college was established in 1893, with a second,complete with darkroom, built in Thompson Hall in1895. In 1910, Brenton L. Steele arrived fromIndiana University as the first full-time physicsinstructor and was appointed assistant professor; asof 1913, Professor Steele was teaching or co-teachingnine different courses: General Physics for Engineers;Non-Mathematical Physics; Methods of TeachingHigh School Physics; Molecular Physics; Heat; Light;Physical Theory of Music; Electricity and Magnetism;and Heat and Illumination. Other classes weredesigned as part of a separate course of study forstudents who had not completed high school:“Mechanic Arts,” taught by Clarence Hix and others,which included such courses as Physics andWoodwork, Household Physics, Modern Physics, andmore. A bachelor’s degree in physics was establishedin 1919 along with the department; Steele was namedchair. Two years later, the department consisted offive faculty members and one teaching fellow, ElsieWorthen.

Anderson arrived in 1931 and was chair of thedepartment for the next 30 years. Anderson’s was astoried background - he earned his Ph.D. at Harvardand then went on to do research at Eastman Kodak,followed by a stint as chair at Yenching University inwhat was then Peking, China. Additionally, he was aNational Research Council Fellow at Harvard and inBerlin.

According to Professor Emeritus Edward E.Donaldson (Ph.D. 1953, Anderson), Andersonbrought an important perspective to the department:the idea that research was a normal activity for anytrained physicist or physics professor, not simply partof the graduate training process. At WSC, Anderson'sresearch was performed in an ultra high vacuumenvironment; the degree of vacuum he achievedcould not be measured or reached by most otherlaboratories for 20 years, and his measurements ofwork functions are still cited today as standard values.Additionally, he and Fitzsimmons decided to developa microscope based on electron wavelengths afterhearing about research being done in Berlin by Ruska

World War II had a lasting positive impact on physicsat WSC/WSU. With the extra funds from the OSRDradar contract, the physics department established amachine/technical shop and purchased war-surplusmachinery. Additionally, the newly-established GI Billmeant a massive influx of new students. Donaldson,chair from 1967-1974 and 1980-1984, was one of thereturning veterans and remembered having to sleepon a gymnasium floor for several weeks while theuniversity built what he called “shanty housing” todeal with the sudden population increase. Butler wasone of the AAF instructors and taught introductoryphysics - as he wrote in an earlier edition of PhysicsMatters, “Each group of men was tested by themilitary before and after this program, and eachschool was rated by departments as to theireffectiveness.” WSC did quite well in comparison tothe rest of the schools.

Faculty members began branching out into differentareas of research as well, notably biophysics(Anderson) and low-energy x-rays (Stephenson).Several importantalumni graduated atthis point - one wasPhil Abelson (M.S.1935, Anderson;WSU DistinguishedAlumnus), who wenton to study with E. O.Lawrence at theUniversity ofCalifornia - Berkeleyuntil 1939 and laterbecame director of theLamont GeophysicalLaboratory, editor ofScience, and director ofthe CarnegieFoundation. Thesecond was Gerald W.Johnson (B.S., M.S. 1939, Stephenson; 1987Alumni Achievement Award), who acted asassociate director of the Lawrence LivermoreNational Laboratory and finally became the personalrepresentative of the United States secretary ofdefense to the Strategic Arms Limitation Talks(S.A.L.T.)

Faculty shone as well: Stephenson’s review article onthe “Continuous X-ray Spectra” published in the 1957edition of Handbuch der Physik, was used as a reference

for decades; Stephenson was named chairman ofphysical sciences in 1947, dean of faculty in 1950, andWSU’s vice president in October 1964, shortly beforehis death in December 1964.

In addition to the flood of veterans and the radarprojects, Wilson Compton became president of WSUin 1944. Compton, brother to well-known physicists K.T. Compton (who studied photo electron energies in1912) and A. H. Compton (who discovered the inelastic“Compton” scattering of x-rays in 1923), understoodthe importance and power of physics and supportedthe department as well as other areas of science andengineering. In 1950, the department moved to thenewly-constructed Technology Building (now DanaHall), which had been designed specifically for physicsresearch by Anderson. The building was extremelysturdy: it was designed to provide vibration isolation toassist with making delicate measurements. Additionally,it had water and electricity routed to every work area;the four-foot-high steam tunnel that housed these was afavorite of students who went exploring late at night.Sometimes, wrote Donaldson in his “Physics History,”researchers working late would notice that “stand pipesconnected near the perimeter tunnel would bob up anddown mysterioussly and whispering voices could beheard.”

The Ph.D. program was established in 1950; by 1952the departmentconsisted ofeight facultymembers, fourstaff members,and 16 graduatestudents. Duringthe early 1960s,William Bandacted as chair - hehad come toPullman after astint in China.Next, from 1967-1974, Edward E.Donaldson hadthis first term aschair, followed byGeorge Duvall

(1974-1976), the founder of the shock physics program.Next came James L. Park (1977-1980), followed againby Donaldson.

Donaldson's second tenure as chair was followed byRichard Fowles (1984-1990), who had been a memberof the faculty since 1966. After Fowles came MichaelMiller, who was chair from 1990-1998 and 1999-2000,with Miles Dresser acting as interim chair from 1998-1999.

As they saw it…

Edward E. Donaldson, 1967-1974; 1980-1984Edward E. Donaldson, professor emeritus, wasinterviewed for this article and provided much of itsoriginal text (as printed in the 1999-2000 edition ofPhysics Matters). Originally from Wenatchee, Washington,he was one of the many young veterans who arrived inPullman after WWII. Donaldson earned all three of hisdegrees at the Pullman campus. In 1953, the newly-

minted Ph.D. headed to Richland in the Tri-Cities to doresearch. However, he didn’t stay away long. When aprofessor was needed at his alma mater, he returned toPullman, where he continues to reside.

Donaldson spoke of his career at WSU as long andrewarding, especially teaching, which was “fun andexciting.” When he began, he was one of only six facultymembers, and worked on a process discovered bycolleagues D. G. Bills and A. Evett in which surfacesreleased metal atoms/molecules. Donaldson was able tochoose which research interests to pursue, which he sayshe enjoyed. Other faculty members were working onsimilar projects, primarily to do with materials structureand metals.

As chair, one of Donaldson’s main responsibilitieswas to recruit new faculty members - he describedhow the department changed over time andeventually added research groups. At first, facultymembers were chosen based on their overall fit ratherthan work in a particular area - it wasn’t until the late1980s that interdisciplinary collaboration becamemore common on campus and research groups beganto form. The Materials Science and EngineeringProgram at WSU was an example he gave ofinstitutionalized collaboration. Ideas crossingdisciplinary lines, in Donaldson’s opinion, can be anexcellent source of innovation and scientific progressand should be encouraged. He said that science andtechnology are advancing so quickly that educationhas had to change over the years to keep up - what’simportant, he said, is not the specific subjects youlearn but being taught how to learn. As for his time aschair, Donaldson said he enjoyed it enough that hetook on a second term, and was particularly proud oftwo of his recruits: Regents Professor J. ThomasDickinson and Donald Sandstrom (now at Boeing).

Steven Tomsovic (2002-2010)Near the turn of the millennium, the departmentbegan to go through several important transitions.From the perspective of Steven Tomsovic, chair from2002-2010, the department not only made severalimprovements in areas such as graduate recruiting andundergraduate education - specifically, hiring “facultywhose main focus was excellence in instruction” - butit also “absorbed significant budget cuts whileminimizing any negative impact.” The departmentalso began to add research in the area of low-temperature physics.

The graduate program in particular underwent majorchanges around the turn of the millennium. TheGraduate Studies Committee members and graduatestudent body made a concerted effort to increase thenumber of graduate students, working in tandem withremarkable success - by 2010, the program had nearlydoubled from 38 students to 70. The addition of theastronomy program (transferred from theDepartment of Mathematics to the Department ofPhysics in 2004) also had an impact - nearly one in sixgraduate applicants applied to work on astronomy-related topics.

The undergraduate program saw changes as well.Dickinson had recently initiated honors physics; thedepartment looked more closely into hiring facultymembers to focus on teaching undergraduate coursesas a means of expanding and continuing to improveas a program. Michael Allen, Nicholas Cerruti,Fred Gittes, and Sudha Swaminathan became thecohort that took on 18 of the department’s classesand worked on curriculum and department-affiliatedprograms, such as the planetarium (Allen and Guy

Worthey) and the Physics & Astronomy Club (Cerruti).In terms of research, Doerte Blume, Bose, and Wortheywere hired, with Peter Engels and Chuanwei Zhang(now at the University of Texas at Dallas) joining thedepartment later.

Matthew McCluskey (2012-present)Originally from Helena, Montana, Matthew McCluskeyarrived at WSU in 1998 from California’s Xerox Palo AltoResearch Center, where he worked on blue lasers andphase separation in InGaN quantum wells. Initially, hisresearch focus at WSU was on the response ofsemiconductors to both static and dynamical pressures;currently, his research group also works on complexoxides and microscopy techniques.

During his time at WSU, McCluskey saw several majordevelopments in the department and university, notablywhat he called “the rise of the graduate program”:“When I arrived at WSU in 1998, we had fewer than 40graduate students. Today we have about 70.” Thedepartment is tightly-knit as well: alumni continue to sendin information about accomplishments and updates,which McCluskey says he loves to hear, and when he hadto be away for some time, the staff, faculty, and graduatestudents all worked together to keep the departmentrunning smoothly. “It was gratifying to see thedepartment pull together like that.”

The department gained two new faculty membersrecently: experimentalist Brian Collins (see p. 14) andtheoristMichael Forbes (see p. 11). McCluskey said thatthe next planned hire is in the area of computationalmaterials physics.
