Query: Supporting random wave models: a quantum mechanical approach   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 exact Green function of the quantum system.
Since no statistical model is required for this derivation, this shows that
taking the wave functions as Gaussian processes is the only assumption of those
random wave models. We also show how for clean systems the two-point
correlation function defined through an energy average defines a Gaussian
theory which substantially reduces the spurious contributions coming from the
normalisation problem.
