Dicke模型中虚光子过程对原子自旋压缩的影响

Influences of the virtual photon process on atom spin squeezing in Dicke model

在经典极限条件下,量子化的Dicke模型在非旋波近似条件下表现为量子混沌动力学特征。本文通过数值计算,考察了Dicke模型中原子自旋压缩性质,讨论了虚光子过程中耦合系数和原子数对原子自旋压缩性质的影响。

Under the condition of classical limit, quantized Dicke model shows the dynamic characteristics of quantum chaos. Ths paper studies the properties of atom spin squeezing in Dicke model by numerical calculation and discusses the influences of coupling parameter and atom numbers in virtual photon process on the characteristics of atom spin squeezing.
