双光子Tavis—Cummings模型中辐射场的振幅平方压缩效应

Amplitud--Squared Squeezing of the field in Two--Photon Tavis--Cummings Model

本文给出了共振情况下双光子Tavis-Cummings模型中光场密度矩阵元的一般表达式,并具体讨论了辐射场的振幅平方压缩效应。

The general expression of the density matrix elements for the field in two-photon Tavis-Cummings model (in resonance case) is derived. The expression, asan example, is used to discuss the amplitude-squared squeezing of the field.
