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…
