摘要：

We show that quantum effects modify the decay rate of Poincare recurrences P(t) in classical chaotic systems with hierarchical structure of phase space. The exponent p of the algebraic decay P(t) proportional to 1/t(p) is shown to have the universal value p = I due to tunneling and localization effects. Experimental evidence of such decay should be observable in mesoscopic systems and cold atoms. [S0031-9007(98)08273-8].
