Resonances for random highly oscillatory potentials

Analysis of PDEs 2018-11-14 v1

Abstract

We study discrete spectral quantities associated to Schr\"odinger operators of the form ΔRd+VN-\Delta_{\mathbb{R}^d}+V_N, dd odd. The potential VNV_N models a highly disordered crystal; it varies randomly at scale N11N^{-1} \ll 1. We use perturbation analysis to obtain almost sure convergence of the eigenvalues and scattering resonances of ΔRd+VN-\Delta_{\mathbb{R}^d}+V_N as NN \rightarrow \infty. We identify a stochastic and a deterministic regime for the speed of convergence. The type of regime depends whether the low frequencies effects due to large deviations overcome the (deterministic) constructive interference between highly oscillatory terms.
