(1) We introduced the concept of "asymptotic ergodicity" as a mathematical formulation of the similarity, under some scaling, of discrete spectrum of a self adjoint operator with a typical realization of a stationary point process. We also showed asymptotic ergodicity forthe spectrum of a certain one dimensional Schroedinger operator, and obtained a partial result for discrete Anderson models.(2) We considered a one dimensional Schroedinger operator H on the half line whose potential term consists of white noise plus a uniform electric field tending to plus infinity. Despite of the singularity of white noise term, we showed that H can be realized as a self-adjoint operator and has purely discrete spectrum, with probability one.
