在回顾了标准的半经典近似波方程的配置空间制定,相干态表示的基础上的方法是充分发展。不同于直接的配置空间的方法,它表明,相干态制定导致一个全球性的,统一的,半经典的配置空间近似,这具有明显的优势,当一个是面对众多的焦散。
Following a review of standard semiclassical approximations to wave equations in the configuration-space formulation, an approach based on a coherent-state representation is fully developed. Unlike direct configuration-space approaches, it is shown that the coherent-state formulation leads to a global, uniform, semiclassical configuration-space approximation, which has distinct advantages when one is faced with numerous caustics.
