弹跳者模型中的不对称输运:混合的,时间相关的,非紧动力学

Asymmetric transport in the bouncer model: Mixed, time dependent, noncompact dynamics

Carl P. Dettmann, Edson D. Leonel

摘要:

我们认为时间依赖性的动态运输,最近的研究体育场台球中,经典的传输和反射概率显示出指数或代数衰减取决于铅或“孔”的选择。这里考虑的系统是更一般的,有一个通用的混合相空间结构,时间依赖的动力学,和费米加速(速度无限的轨迹)。我们提出了一个有效的数值方案,观察非对称输运效应,并讨论所观察到的拉伸指数衰减。

英文摘要:

We consider time-dependence of dynamical transport, following a recent study of the stadium billiard in which classical transmission and reflection probabilities were shown to exhibit exponential or algebraic decay depending on the choice of the lead or "hole". The system considered here is much more general, having a generic mixed phase space structure, time-dependence of the dynamics, and Fermi acceleration (trajectories with unbounded velocity). We propose an efficient numerical scheme for this model, observe the asymmetric transport effect, and discuss observed stretched exponential decays.
