摘要
本文研究了双光子Tavis—Cummings模型中原子算符的时间演化,分别给出了光场为粒子数迭加态和相干态情况下,双原子算符的压缩行为,并讨论了在激光场作用下,双原子协变呈现的崩溃与回复现象。
In this paper, the time evolution of the two--atom operators in the two photonTavis--Cummings Model have been investigated. The atomic squeezing effects areshown when the field is the superposition state of the number states and coherentstate respectively. The phenomenon of the atomic decay and revival is also dis-cussed when the two atoms interact with coherent radiation.
