克尔非线性黑体的Q函数分布

The Distribution of Q Function in a Kerr Nonlinear Blackbody

在普通黑体内部充满一种克尔非线性晶体,这种黑体称为克尔非线性黑体。在克尔非线性黑体中,具有相反波矢和自旋的裸光子结合成对,不成对的裸光子转换成一种新的准粒子-非极化激元。利用Q函数具体研究了克尔非线性黑体光场的相位分布情况。通过分析克尔非线性黑体光场的Q函数分布情况发现,温度和耦合系数对相位分布有很大的影响,同时观察到了光场的压缩效应:随着温度的降低,光场由常态变为压缩态,光场相位对移自发破缺。

A Kerr nonlinear blackbody was a blackbody whose interior was filled by a Kerr nonlinear crystal.By analyzing the distribution of phase with Q function in a Kerr-nonlinear blackbody,it is found that the distribution of phase is strongly influenced by temperature and coupling parameter.Non-classical effects of quadrature squeezing is observed.
