All couplings localization for quasiperiodic operators with Lipschitz monotone potentials

Abstract

We establish Anderson localization for quasiperiodic operator families of the form $$(H(x)\psi )(m)=\psi (m+1)+\psi (m-1)+\lambda v(x+m\alpha )\psi (m)$$ for all $\lambda >0$ and all Diophantine $\alpha$, provided that $v$ is a $1$-periodic function satisfying a Lipschitz monotonicity condition on $[0,1)$. The localization is uniform on any energy interval on which Lyapunov exponent is bounded from below.
