摘要：

A two-level system subject to quasiperiodically modulated kicking is investigated under the aspects of ergodic theory. For weak kicking strength the correlation functions exhibit quasiperiodic behavior, whose character changes with increasing as recurrences become infrequent. A quantum instability with a transition to mixing behavior that was suggested for similar models does not arise. Analytic results are obtained for the case where two of three characteristic frequencies are incommensurate. © 1990 The American Physical Society.
