依赖强度耦合的Jaynes－Cummings模型中辐射场的位相性质

The Phase Properties of the Radiation Field in the Intensity -dependent Coupling Jaynes-Cummings Model

利用共振条件下的依赖强度耦合Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型，研究辐射场与原子相互作用后的各种位相性质，并与相干态的位相相比较。可以看出，适当选择参数，可使位相膨胀实现压缩。

By the use of the intensity-dependent coupling Jaynes-Cummings model under the resonance condition, the phase properties of radiation field after the interaction of atoms are discussed, and compared with the phase of coherent state, it is discovered that the phase expansion can be squeezed by selecting suiltable parameters.
