Quantum diffusion in the Harper model under polychromatic time-perturbation
Hiroaki S. Yamada, Kensuke S. Ikeda
Quantum dynamics of the Harper model with self-duality exhibits localized, diffusive, and ballistic states depending on the potential strength . By adding time-dependent harmoni…

Quantum Diffusion Induced by Small Quantum Chaos
Hiroaki S. Yamada, Kensuke S. Ikeda
It is demonstrated that quantum systems classically exhibiting strong and homogeneous chaos in a bounded region of the phase space can induce a global quantum diffusion. As an idea…
