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…

Approximating the density of states for Poisson distributed random Schroedinger operators

David Hasler, Jannis Koberstein

We consider a Schroedinger operator with random potential distributed according to a Poisson process. We show that expectations of matrix elements of the resolvent as well as the d…

On asymptotic expansions of resolvents for Poisson distributed random Schrödinger operators

David Hasler, Jannis Koberstein

We study expectation values of matrix elements of the resolvent for a random Schrödinger operator with potential distributed according to a Poisson process. Asymptotic expansions f…

A note on the surjectivity of operators on vector bundles over discrete spaces

Jannis Koberstein, Marcel Schmidt

In this note we give a short and self-contained proof for a criterion of Eidelheit on the solvability of linear equations in infinitely many variables. We use this criterion to stu…
