We propose a new way of studying the Riemann zeros on the critical line using ideas from supersymmetry. Namely, we construct a supersymmetric quantum mechanical model whose energy eigenvalues correspond to the Riemann zeta function in the strip 0 < Re s < 1 (in the complex parameter space) and show that the zeros on the critical line arise naturally from the vanishing ground state energy condition in this model.
Riemann [1]generalized Euler's zeta function to the entire complex space of parameters in three essential steps. First, he extended the series representation of the zeta function to complex parameters asThis series representation can be written as a product of factors involving only prime numbers and the zeta function in (1) has an integral representation in terms of the Mellin transform of the Bose-Einstein distribution function [2]. In the second step, he expressed the zeta function in (1) in terms of the alternating zeta function asThis leads to an integral representation of the zeta function in terms of the Mellin transform of the Fermi-Dirac distribution function [2]. In this way, Riemann had defined the zeta function on the right half of the complex parameter space except for the point s = 1. In order to extend it to the left half of the plane, Riemann derived two equivalent functional relations (we give only one, the other can be obtained from this by letting s → 1 − s)This, therefore, generalizes the zeta function to the entire complex plane. The zeta function is an analytic function [3,4] which has a simple pole at s = 1 with residue 1 (the pole structure is already manifest in (2)). It vanishes for s = −2k where k ≥ 1 which can be seen from (3). These zeros are known as "trivial" zeros of the zeta function since they arise from the kinematic trigonometric factor in (3) and are the only zeros for Re s ≤ 0 (ζ(0) = − 1 2 ). Furthermore, from the representation of the zeta function in terms of products involving prime numbers, it can be shown that the zeta function has no zero for Re s > 1 (since none of the factors can vanish there). Therefore, any other "non trivial" zero of the zeta function must lie in the strip 0 < Re s < 1.(4)Riemann conjectured [1] that all other zeros of the zeta function lie on the critical line Re s = 1 2 , namely,where λ * denotes the location of a zero on the critical line. This is known as the Riemann hypothesis and so far many zeros have been calculated on the critical line numerically [5,6]. Note that the Riemann hypothesis specifies only the real part of the parameter s at a zero. It does not say anything about the location (imaginary part of the parameter s) on the critical line. The numerical calculations do not yet show any particular recurrence relation or regularity in the locations of the zeros. There is a fascinatingly beautiful symmetry in physics known as supersymmetry [7][8][9][10]. It has a simple manifestation in one dimensional supersymmetric quantum mechanics [11][12][13][14] where there are two conserved charges, Q, Q † satisfying the graded algebra (t...
