On multiplicity of spectrum for Anderson type operators with higher rank perturbations

Anish Mallick, P A Narayanan

Here, we focus on Anderson type operators over infinite graphs where the randomness acts through higher rank perturbations. We show that for special family of graphs, the operator…

Level spacing and Poisson statistics for continuum random Schrödinger operators

Adrian Dietlein, Alexander Elgart

We prove a probabilistic level-spacing estimate at the bottom of the spectrum for continuum alloy-type random Schrödinger operators, assuming sign-definiteness of a single-site bum…

Full Szegő-type trace asymptotics for ergodic operators on large boxes

Adrian Dietlein

We prove full Szegő-type large-box trace asymptotics for selfadjoint $Z^{d}$ -ergodic operators $Ω ∋ ω \mapsto H_{ω}$ acting on $L^{2} (R^{d})$ . More precisely, let $g$ be…

Perturbations of continuum random Schrödinger operators with applications to Anderson orthogonality and the spectral shift function

Adrian Dietlein, Martin Gebert, Peter Müller

We study effects of a bounded and compactly supported perturbation on multi-dimensional continuum random Schrödinger operators in the region of complete localisation. Our main emph…

A bound on the averaged spectral shift function and a lower bound on the density of states for random Schrödinger operators on $R^{d}$

Adrian Dietlein, Martin Gebert, Peter D. Hislop +2

We obtain a bound on the expectation of the spectral shift function for alloy-type random Schrödinger operators on $R^{d}$ in the region of localisation, corresponding to a…
