Wegner estimate and localization for alloy-type models with sign-changing exponentially decaying single-site potentials

Karsten Leonhardt, Norbert Peyerimhoff, Martin Tautenhahn +1

We study Schrödinger operators on $L^2 (\RR^d)$ and $\ell^2(\ZZ^d)$ with a random potential of alloy-type. The single-site potential is assumed to be exponentially decaying but not…
