Dynamical Localization as Quantum Thinning: A Thinness Ratio for Microwave Hydrogen and the Kicked Rotator
This paper asks a narrower question than whether a quantum system is chaotic. It asks whether quantum transport reaches a stated failure scale over a stated horizon. The setting is dynamical localization, where momentum or photon-number diffusion in a classically chaotic Floquet system stops after a break time because...
