Dynamical Tunneling in Many-Dimensional Chaotic Systems
Dynamical Tunneling in Many-Dimensional Chaotic Systems
We investigate dynamical tunneling in many-dimensional systems using a quasiperiodically modulated kicked rotor, and find that the tunneling rate from the torus to the chaotic region is drastically enhanced when the chaotic states become delocalized as a result of the Anderson transition. This result strongly suggests that amphibious states, which …
