Anderson Localization For The Quantum Kicked Rotor Model

Abstract

In this paper, we establish Anderson localization for the quantum kicked rotor model. More precisely, we proved that \begin{equation*} H=\tan\pi\left(x_0+my_0+\frac{m(m-1)}{2}\omega\right) \delta_{mn}+\epsilon S_\phi \end{equation*} has pure point spectrum with exponentially decaying eigenfunctions for almost all $\omega \in DC$ (diophantine condition).
