| Outline of Final Research Achievements |
We have numerically investigated some classical and quantal aspects of many dimensional chaos by paying a special emphasis on the localization and non-localization(diffusion) of probability flow.
(1)For classical systems, we elucidate the relationship between chaotic dynamics and micro-canonical transition state theory in the isomerization dynamics of a Lennard-Jones cluster in terms of the lifetime distributions for stable isomers. Moreover,(2)we developed a novel numerical method to extract the bottleneck process (the slowest relaxation mode) from the complicated transition network among stable states.(3)For quantum map systems, we have found a phenomenological scaling rule for the localization length, which can be derived by the self-consistent mean-field theory on the basis of a new hypothesis.The localization to non-localization transition in multidimensional quantum chaotic maps has been discussed by means of the so-called quantum coupled kicked rotor.
