摘　　要：应用全量子理论 ,研究了非旋波近似下与双模压缩真空场相互作用的二能级原子算符的时间演化规律和偶极压缩性质 ,数值计算结果表明 ,虚光场效应主要表现为物理过程中的量子噪声 ,这种量子噪声的大小与光场的初始压缩参量和原子的初始状态以及系统的耦合强度等因素密切相关 .We have investigated in the time\|evolution and the squeezing character of atomic operators in a system of two\|mode squeezed vacuum field interacting with a two\|level atom without the rotating\|wave approximation by means of quantum theory.The results obtained using the numerical method indicate that the influence of the virtual\|photon field on the atomic quantum character is mainly the cause for quantum chaos which is related to the quantum character of the system itself.
