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…
