On asymptotic expansions of the density of states for Poisson distributed random Schrödinger operators
Jan Fischer, David Hasler, Jannis Koberstein
We study a random Schrödinger operator with a potential distributed according to a Poisson process. Asymptotic expansions for traces of resolvents in the limit of small disorder ar…

Limits of spectral measures for linearly bounded and for Poisson distributed random potentials
David Hasler, Jannis Koberstein
We show the existence of infinite volume limits of resolvents and spectral measures for a class of Schroedinger operators with linearly bounded potentials. We then apply this resul…
