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…
