双模SU(1,1)相干态场与两个原子相互作用的动力学特性

Dynamical Properties of TwoMode SU(1,1) Coherent StatesInteracting with Two Atoms

研究了双模ＳＵ（１，１）相干态场与两个二能级原子相互作用过程中原子的动力学行为和双模场的量子性质，讨论了原子间的偶极相互作用对它们的影响。结果表明：原子间的耦合系数满足一定条件时，辐射场呈周期性压缩。

? We study the dynamic behavior of atoms and the quantum properties of the field under the interaction of twomode SU(1,1) coherent state with two twolevel atoms, and discuss how they are modified by dipoledipole interaction. The numerical results show that the twomode squeezing of the field exhibit periodic behavior as time evolves while atomatom couple coefficient meet certain condition.
