相干态的现状
The Current State of Coherent States
摘要：
最初的正则相干态可以用几种方式定义。随着其他相干态的应用出现，定义规则也相应地改变了。在这些规则的变化中，有一个群体的变化和标签分析性质的放松。最近的发展已经完全消除了群的联系，从而允许定义一组相干态，这些相干态对于包括氢原子在内的各种动力学系统都是暂时稳定的。本文概述了当前相干态的定义和性质的一些趋势。
英文摘要：
The original canonical coherent states could be defined in several ways. As applications for other sets of coherent states arose, the rules of definition were correspondingly changed. Among such rule changes were a change of group and relaxation of the analytic nature of the labels. Recent developments have done away with the group connections altogether and thereby allowed sets of coherent states to be defined that are temporally stable for a wide variety of dynamical systems including the hydrogen atom. This article outlines some of the current trends in the definitions and properties of present-day coherent states.
