Universal spectral statistics in quantum graphs

Chaotic Dynamics 2009-11-10 v2 Mesoscale and Nanoscale Physics

Abstract

We prove that the spectrum of an individual chaotic quantum graph shows universal spectral correlations, as predicted by random--matrix theory. The stability of these correlations with regard to non--universal corrections is analyzed in terms of the linear operator governing the classical dynamics on the graph.
