Idea

The Bost-Connes system (Bost-Connes 95) is the semigroup crossed product C*-algebra C *(/) ×C^\ast(\mathbb{Q}/\mathbb{Z})\rtimes \mathbb{N}^\times equipped with a canonical 1-parameter flow texp(tH)t\mapsto\exp(-t H), and as such thought of as a quantum mechanical system.

The point is that the partition function of this system is the Riemann zeta function (Bost-Connes 95, theorem 5 (c) (page 6)).

Alain Connes has proposed that via this relation there might be a way to shed insight on the Riemann hypothesis using tools from quantum mechanics and statistical mechanics (Connes-Marcolli 06). See also at Riemann hypothesis and physics.
