Quantum Recurrence Theorem for the Riemann Zeta Function: A New Dynamical Property of the Zeta Zeros

<jats:p>We prove a quantum recurrence theorem for the Riemann zeta function. Using the evolution operator Ĥα(t) = e^{itHα}Kαe^{-itHα}, we show that the system exhibits quantum recurrence precisely on the critical line α = 1/2. Specifically, for any ε &gt; 0 and any ψ ∈ D, there exists a sequence of times t_n → ∞ such that ||Ĥ_{1/2}(t_n)ψ - ψ|| &lt; ε. For α ≠ 1/2, no such recurrence occurs: there exists ψ ∈ D and ε_0 &gt; 0 such that for all t, ||Ĥ_α(t)ψ - ψ|| ≥ ε_0. This establishes a new dynamical characterisation of the critical line and provides a physical interpretation of the Riemann Hypothesis: the zeros of ζ(s) are the "energy levels" of a quantum system that exhibits recurrence exactly at the critical line. The theorem is rigorously proven using the spectral properties of Hα, the explicit formula for the coherence kernel, and the twin operator method.</jats:p>
