Lifshits Tails for Squared Potentials
arXiv:1704.01435 · doi:10.1007/s00023-018-0680-8
Abstract
We consider Schrödinger operators with a random potential which is the square of an alloy-type potential. We investigate their integrated density of states and prove Lifshits tails. Our interest in this type of models is triggered by an investigation of randomly twisted waveguides.
