Arithmetic version of anderson localization for quasiperiodic Schr\"odinger operators with even cosine type potentials
Abstract
We propose a new method to prove Anderson localization for quasiperiodic Schr\"odinger operators and apply it to the quasiperiodic model considered by Sinai and Fr\"ohlich-Spencer-Wittwer. More concretely, we prove Anderson localization for even C2 cosine type quasiperiodic Schr\"odinger operators with large coupling constants, Diophantine frequencies and Diophantine phases.
