摘要

本文利用微扰方法研究了与Dicke模型中N个两能级原子系统通过单光子及双光子过程相互作用的相干态场的时间演化

研究表明

若单光子和双光子Dicke模型中的N个两能级原子初始时皆处于去激发状态

则在初始短时间内可产生场的振幅k次方压缩

且场的振幅k次方压缩态是场振幅k次方的正交分量的最小测不准态。

Abstract

A perturbative method was used to study the time evolution of a coherent state interacting with a group of two-level atoms via one-photon and two-photon processes in the Dicke model. It is shown that

as in the one-photon and two-photon models

amplitude kth-power squeezing is produced over the initial short time and the amplitude kth-power squeezing state of the field are minimum uncertainty states in the quadrature components of the kth-power of the field amplitude if the atoms are only initially completely de-excited.
