相干态和压缩态的简单介绍

A pedestrian introduction to coherent and squeezed states

Bijan Bagchi, Rupamanjari Ghosh, Avinash Khare

摘要:

本文旨在帮助读者快速了解相干态和压缩态的理论基础。相干态和压缩态通常是由谐振子产生的,但并不总是局限于谐振子。注意到建立这种态的方法有很长的历史,我们收集了重要的元素,并从一个新的角度复制它们,但没有深入研究每个主题的详细推导。我们决不要求全面介绍这个问题,而只是试图重新捕捉一些重要的结果,并指出它们之间的相互联系。

英文摘要:

This review is intended for readers who want to have a quick understanding on the theoretical underpinnings of coherent states and squeezed states which are conventionally generated from the prototype harmonic oscillator but not always restricting to it. Noting that the treatments of building up such states have a long history, we collected the important ingredients and reproduced them from a fresh perspective but refrained from delving into detailed derivation of each topic. By no means we claim a comprehensive presentation of the subject but have only tried to re-capture some of the essential results and pointed out their inter-connectivity.
