Contribution

It introduces a numerical approach to study the crossover between Anderson localization and the photoelectric effect in driven atomic systems.

Findings

Demonstrates the transition from localization to ionization behavior

Provides numerical evidence of the crossover dynamics

Connects localization phenomena with atomic ionization processes

Abstract

We study the counterpart of Anderson localization in driven one-electron Rydberg atoms. By changing the initial Rydberg state at fixed microwave frequency and interaction time, we numerically monitor the crossover from Anderson localization to the photo effect in the atomic ionization signal.
