Arithmetic localization for quasiperiodic long-range operators with monotone potentials

We study one-dimensional quasiperiodic operators with $α$-Hölder monotone potentials and long-range hopping satisfying $|T(x,y)|\leq \varepsilon e^{-ρ|x-y|}$. Under an explicit smallness condition on $\varepsilon$, we establish uniform Anderson localization for such operators in the regime $ρ>αβ$, where $β$ is the exponential strength of frequency resonances. Our proof extends the arithmetic localization strategy for monotone quasiperiodic Schrödinger operators by Jitomirskaya and Kachkovskiy to the long-range setting, without relying on the Lyapunov exponent.

Abstract

We study one-dimensional quasiperiodic operators with $α$-Hölder monotone potentials and long-range hopping satisfying $|T(x,y)|\leq \varepsilon e^{-ρ|x-y|}$. Under an explicit smallness condition on $\varepsilon$, we establish uniform Anderson localization for such operators in the regime $ρ>αβ$, where $β$ is the exponential strength of frequency resonances. Our proof extends the arithmetic localization strategy for monotone quasiperiodic Schrödinger operators by Jitomirskaya and Kachkovskiy to the long-range setting, without relying on the Lyapunov exponent.
