| Outline of Final Research Achievements |
Classical and quantum chaos are ubiquitous phenomena in our world.Recently,it was suggested that a hidden connection between classical and quantum chaos may exist, and also that it was predicted that there is a universal upper bound on the strength of chaos,independent of the system's details. If this prediction is confirmed, it could shed light on the nature of various chaotic phenomena and potentially contribute to clalifying the origin of the black hole entropy, which is one of the longstanding problems in modern physics. In this research project, we try to verify this prediction and also examine its extendability employing the gauge-gravity correspondence, which connects classical gravity theory with quantum field theory. We also discuss dynamical phenomena in the context of gauge-gravity correspondence, which could be useful to study chaotic phenomena in classical and quantume systems.
