Dynamical Tunneling in Many-Dimensional Chaotic Systems
Akiyuki Ishikawa, Atushi Tanaka, Akira Shudo
We investigate dynamical tunneling in many dimensional systems using a quasi-periodically modulated kicked rotor, and find that the tunneling rate from the torus to the chaotic reg…
Recovery of chaotic tunneling due to destruction of dynamical localization by external noise
Akiyuki Ishikawa, Atushi Tanaka, Akira Shudo
Quantum tunneling in the presence of chaos is analyzed, focusing especially on the interplay between quantum tunneling and dynamical localization. We observed flooding of potential…
Quantum suppression of chaotic tunneling
Akiyuki Ishikawa, Atushi Tanaka, Akira Shudo
The interplay between chaotic tunneling and dynamical localization in mixed phase space is investigated. Semiclassical analysis using complex classical orbits reveals that tunnelin…
Continuum Annulus Amplitude from the Two-Matrix Model
M. Anazawa, A. Ishikawa, H. Itoyama
An explicit expression for continuum annulus amplitudes having boundary lengths and is obtained from the two-matrix model for the case of the unitary series;…
