Résumé :
As is well known, different types of localization phenomena, such as dynamical localization, localization on invariant tori, localization on unstable periodic orbits, appear simultaneously in the quantum system whose classical phase space is composed of regular and chaotic components. Each has its own origin and a different classical invariant set as its support. However, they coexist in a single phase space, one would expect that they are affected by each other and correlated under a certain consistent rule. Here we will show that a strong interplay indeed exists between dynamical localization and localization on invariant tori, and discuss how one quantum effect is suppressed by another quantum effect.
