摘要
本文研究了初始辐射场为由ＳＵ（１，１）相干态描述的压缩真空态时，Ｓｔａｒｋ效应对双光子ＪａｙｎｅｓＣｕｍｍｉｎｇｓ模型中原子和场的压缩效应，以及光子的反聚束效应的影响。作为比较，本文也讨论了初始辐射场为相干态光场时原子和场的动力学特性。
For an initial squeazed vacuum state described as an SU(1,1) coherent state,we study the effect of the Stark shift on the squeezing of atomic dipole and field,as well as the antibunching of photons in the two-photon Jaynes-Cummings model,and compare them with that for a coherent light input of the same intensity.
