Are the square of the imaginary part of the Riemann Zeros 2n nE
So the Energies of the Hamiltonian are the roots of the Riemann Xi-function\Riemann zeta function

The Riemann Xi-function can be expressed as a functional determinant on the variAble ‘s’
The Riemann-Weil trace formula can be obtained from the derivative of the folloWing functional determinant

In order to get the proof that our quantum system defined on page first , gives theSquare of the zeros of the Riemann zeta function as Eigenvalues, we need to intro-Duce 2 important formulae , the Riemann-Weil explicit formula and the quantizationRules by Bohr and Sommerfeld

BOHR-SOMMERFELD QUANTIZATION RULE
Here, n=n(E) is an integer this formula is an approximation but works pretty well For big values of the Quantum Energies ‘n’ , the pont ‘a’ is a turning point so the Momentum of the particle is p=0 and E=V(a) , in one dimension we can obtain The potential (its inverse) from the eigenvalue staircase as follows

The constant integration is set to 0 so at x=0 the potential and the n(E) take the Value 0 , from this equation above we have proved that we can recover the inverseOf the potential (and hence the potential) from the half derivative of the EigenvalueStaircase
If we introduce the momentum and wave number in terms of the Energy

This is made in order to simplify the calculations and avoid constants

In this case the density of states is related to a sum over primes, this is not new For example for the infinite potential well the density of Energies can be evaluatedBy an exponential sum over ALL the integers.
The sum involving the Dirac delta is over the zeros of f(x) E p k The sum involving the Mangoldt function has been zeta-regularized
The sum over the imaginary part of the zeros inside the Riemann-Weil formula isOver ALL the zeros, not just the zeros lying on the critical line Re(s)=1/2

A simpler analogy is given by the hyperbolic sine function and the infinite potenTial well in QM in this case the problem is exactly solvable and gives.
So , we can expect that our method will work, HOWEVER in order to work we NEED to include both, the SMOOTH and oscillating part of the Eigenvalue StairCase N(E) , otherwise the results may be poor
