Abstract

We establish Anderson localization for quasiperiodic operator families of the form (H(x)ψ)(m)=ψ(m+1)+ψ(m1)+λv(x+mα)ψ(m) (H(x)\psi)(m)=\psi(m+1)+\psi(m-1)+\lambda v(x+m\alpha)\psi(m) for all λ>0\lambda>0 and all Diophantine α\alpha, provided that vv is a 11-periodic function satisfying a Lipschitz monotonicity condition on [0,1)[0,1). The localization is uniform on any energy interval on which Lyapunov exponent is bounded from below.
