使用一个简单的方法,类似于一个量子rephasing技术,一个简单的修改经典和量子混沌的范例。由此获得的有趣的量子映射显示出非常丰富的量子动力学。重点放在不破坏周期性的动力学局域化的破坏,可积系统中的无界量子反常扩散和瞬态动力学局域化。这项工作的实验实现进行了讨论。
Using a simple method analogous to a quantum rephasing technique, a simple modification to a paradigm of classical and quantum chaos is proposed. The interesting quantum maps thus obtained display remarkably rich quantum dynamics. Emphasis is placed on the destruction of dynamical localization without breaking periodicity, unbounded quantum anomalous diffusion in integrable systems, and transient dynamical localization. Experimental realizations of this work are also discussed.
