Random Wave Functions with boundary and normalization constraints: Quantum statistical physics meets quantum chaos
Juan Diego Urbina, Klaus Richter
We present an improved version of Berry's ansatz able to incorporate exactly the existence of boundaries and the correct normalization of the eigenfunction into an ensemble of rand…

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…
