高斯型特征函数光场的密度算符及其非经典性质

Density Operator and Nonclassical Properties of the Field with Gaussian Character Function

本文给出了具有高斯型特征函数光场的密度算符，讨论了这类光场的各种非经典性质，并详细分析了其中各因子的物理意义以及光场是经典或非经典的条件。结果表明，光场特征函数是一个物理意义十分明显、有很大优越性的光场表示。

Density operator and various nonclassical properties of the field with Gaussian character function is given in this paper.The physical meanings of all factors in it and its classical or nonclassical conditions are analyzed in detail. The results show that field character function is a field presentation with very clear physical meaning and great superiority.
