Spectral Properties of the Discrete Random Displacement Model

Roger Nichols, Günter Stolz

We investigate spectral properties of a discrete random displacement model, a Schrödinger operator on $ℓ^{2} (Z^{d})$ with potential generated by randomly displacing finitely suppor…

Simplicity of eigenvalues in Anderson-type models

Sergey Naboko, Roger Nichols, Günter Stolz

We show almost sure simplicity of eigenvalues for several models of Anderson-type random Schrödinger operators, extending methods introduced by Simon for the discrete Anderson mode…
