摘要:

我们研究了经典粒子与一个、两个、最后是一个具有振荡深度的一维方阱的无限长链相互作用的运动。对于单阱,我们发现复杂的散射行为,即使没有拓扑混沌,由于双曲周期轨道的情况下。相反,对于两个耦合方阱,存在混沌散射。无限振荡链产生的通用过渡到混沌,在能量和空间中的扩散,作为井之间的分离增加。我们简要地讨论了我们的结果的相关性,固态物理。

英文摘要:

We study the motion of a classical particle interacting with one, two, and finally an infinite chain of 1D square wells with oscillating depth. For a single well we find complicated scattering behavior even though there is no topological chaos due to the absence of hyperbolic periodic orbits. In contrast, for two coupled square wells there is chaotic scattering. The infinite oscillating chain yields the generic transition to chaos, with diffusion in energy and in space, as the separation between wells is increased. We briefly discuss the relevance of our results to solid state physics.
