摘要：

A mechanism for the fluctuating features associated with the general phenomenon known as chaos-assisted tunneling is presented. These features are shown to be the result of a gradual competition between classically allowed (mixing) and classically forbidden (tunneling) dynamical processes. A random-matrix description of the phenomenon is provided. This requires, apart from the statistical ensembles commonly used to represent mixing, logarithmic-random ensembles to describe tunneling. Appearance and disappearance of tunneling partners and suppression of tunneling are predicted as possible features of chaos-assisted tunneling regions.
