On the Lipschitz continuity of the integrated density of states for sign-indefinite potentials
Vadim Kostrykin, Ivan Veselic
The present paper is devoted to the study of spectral properties of random Schroedinger operators. Using a finite section method for Toeplitz matrices, we prove a Wegner estimate f…
Integrated density of states and Wegner estimates for random Schrödinger Operators
Ivan Veselic'
We survey recent results on spectral properties of random Schrödinger operators. The focus is set on the integrated density of states (IDS). First we present a proof of the existen…
Existence of the density of states for some alloy type models with single site potentials of changing sign
Ivan Veselic'
We study spectral properties of ergodic random Schrödinger operators on $L^2 (\RR^d)$. The density of states is shown to exist for a certain class of alloy type potentials with sin…
Existence of the density of states for one-dimensional alloy-type potentials with small support
Werner Kirsch, Ivan Veselic'
We study spectral properties of Schrödinger operators with random potentials of alloy type on $L^2(\RR)$ and their restrictions to finite intervals. A Wegner estimate for non-negat…
