Lifetime of the arrow of time inherent in chaotic eigenstates: case of coupled kicked rotors
Fumihiro Matsui, Hiroaki S. Yamada, Kensuke S. Ikeda
A linear oscillator very weakly coupled with the object quantum system is proposed as a detector measuring the lifetime of irreversibility exhibited by the system, and classically…
Critical Phenomena of Dynamical Delocalization in Quantum Anderson Map
Hiroaki S. Yamada, Fumihiro Matsui, Kensuke S. Ikeda
Using a quantum map version of one-dimensional Anderson model, the localization-delocalization transition of quantum diffusion induced by coherent dynamical perturbation is investi…
Instanton-noninstanton transition in nonintegrable tunneling processes: A renormalized perturbation approach
Akira Shudo, Yasutaka Hanada, Teruaki Okushima +1
The instanton-noninstanton (I-NI) transition in the tunneling process, which has been numerically observed in classically nonintegrable quantum maps, can be described by a perturba…
Origin of the enhancement of tunneling probability in the nearly integrable system
Yasutaka Hanada, Akira Shudo, Kensuke S. Ikeda
The enhancement of tunneling probability in the nearly integrable system is closely examined, focusing on tunneling splittings plotted as a function of the inverse of the Planck's…
