半经典理论预言,如果Escherfest时间超过在腔中的停留时间,则对弹道混沌腔电导的弱局域化修正被抑制[I]。L. Aleiner和A. I. Larkin,B 54,14423(1996)]。我们报告的数值模拟弱本地化的开放量子踢旋转器,证实了这一预测。我们的结果不同意通过弹道混沌腔输运的“有效随机矩阵理论”。
Semiclassical theory predicts that the weak localization correction to the conductance of a ballistic chaotic cavity is suppressed if the Ehrenfest time exceeds the dwell time in the cavity [I. L. Aleiner and A. I. Larkin, Phys. Rev. B 54, 14423 (1996)]. We report numerical simulations of weak localization in the open quantum kicked rotator that confirm this prediction. Our results disagree with the "effective random matrix theory" of transport through ballistic chaotic cavities.
