论文摘要
踢的转子和踢顶是两个量子混乱的范式。在踢旋翼研究中发展的量子共振和伪经典极限的概念显示出古典量词对应关系的有趣且非常规的方面。在这里，我们表明，通过将这些概念扩展到踢顶，可以更彻底地理解其丰富的动态行为。特别感兴趣的是纠缠熵。特别是，从伪经典的角度可以方便地理解和详细说明受不同踢球强度的系统之间的周期性同步。还讨论了建议的一般伪古典理论对踢旋翼的适用性。
The kicked rotor and the kicked top are two paradigms of quantum chaos. The notions of quantum resonance and the pseudoclassical limit, developed in the study of the kicked rotor, have revealed an intriguing and unconventional aspect of classical-quantum correspondence. Here, we show that, by extending these notions to the kicked top, its rich dynamical behavior can be appreciated more thoroughly; of special interest is the entanglement entropy. In particular, the periodic synchronization between systems subject to different kicking strength can be conveniently understood and elaborated from the pseudoclassical perspective. The applicability of the suggested general pseudoclassical theory to the kicked rotor is also discussed.
