Statistical description of eigenfunctions in chaotic and weakly disordered systems beyond universality
Juan Diego Urbina, Klaus Richter
We present a semiclassical approach to eigenfunction statistics in chaotic and weakly disordered quantum systems which goes beyond Random Matrix Theory, supersymmetry techniques, a…

Supporting random wave models: a quantum mechanical approach
J. D. Urbina, K. Richter
We show how two-point correlation functions derived within non-isotropic random wave models are in fact quantum results that are obtained in the appropriate limit in terms of the e…
