The Riemann ζ-Function in Phase Space — •Cornelia Feiler, Rüdiger Mack, and Wolfgang P. Schleich — Institute for Quantum Physics, Ulm University

The Riemann hypothesis, a conjecture about the distribution of the so called non-trivial zeros of the Riemann ζ-function, is at the very heart of number theory. The distribution of these zeros is strongly connected with the distribution of primes [1]. Prime numbers, on the other hand, play a crucial role for example in cryptography or factorization.

We propose a new physical approach to the Riemann ζ-function. We consider the states of an harmonic oscillator with a logarithmic coupling to an external field. With an appropriate projection we obtain the values ζ(s) for ℜ s>1. With the help of an entangled system, similar to the Jaynes-Cummings-Model [3], we managed to reach into the critical strip, where the non-trivial zeros of the ζ-function are expected to be.
