电磁场压缩的非标准引论

Nonstandard introduction to squeezing of the electromagnetic field

Iwo Bialynicki-Birula

摘要:

本文回顾了完全基于压缩态的波函数描述的另一种压缩理论。利用量子场论方法,考虑了压缩态的时空特性,给出了电磁场压缩的最完整形式。介绍了一种模拟全电磁场的维格纳函数,并用二阶关联函数表示。场论方法使人们能够研究时空中“压缩波”的传播。一个简单的例子,弱压缩,允许所有的计算进行分析,详细讨论。

英文摘要:

This article contains a review of an alternative theory of squeezing, based entirely on the wave function description of the squeezed states. Quantum field theoretic approach is used to describe the squeezing of the electromagnetic field in its most complete form that takes into account temporal and spatial characteristics of the squeezed state. An analog of the Wigner function for the full electromagnetic field is introduced and expressed in terms of second order correlation functions. The field-theoretic approach enables one to study the propagation of the ``squeezing wave'' in space-time. A simple example of weak squeezing, that allows for all calculations to be done analytically, is discussed in detail.
