Abstract

We present a semiclassical approach to eigenfunction statistics in chaotic and weakly disordered quantum systems which goes beyond random matrix theory, supersymmetry techniques, and existing semiclassical methods. The approach is based on a generalization of Berry’s random wave model, combined with a consistent semiclassical representation of spatial two-point correlations. We derive closed ...
