Jaynes－Cummings模型中辐射场的振幅N次方压缩特性

THE Nth POWEER SQUEEZING OF FIELD AMPLITUDE IN THE JAYNES-CUMMINGS MODEL

本文研究了一初始处于激发态的二能级原子与相干态光场相互耦合的Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型中场的振幅Ｎ次方压缩特性，给出了其压缩度随光场的初始平均光子数和压缩阶数的变化规律。

The properties of the N th-power squeezing of field amplitude in the Jaynes-Cummingsmodel of an atom initially in the extited state coupling vvith the coherent state are investigated in thispaper;The variations of the degree of the squeezing with the initial average photon number of field andthe power N of the squeezing are discussed.
