真空态多光子Jaynes－Cummings模型中场熵的演化

Evolution of the Field Entropy in the Vacuum-state Multiphoton Jaynes-Cummings Model

研究真空态多光子Ｊ－Ｃ模型中场熵演化特性，讨论原子相干性、失谐量和跃迁光子数的影响，并与热光场、相干光场Ｊ－Ｃ模型中场熵演化进行了比较．

in this paper,the properties of the evolution of the field entropy in the vacuum-state multiphoton J-C model have been investigated.The influences of atomic coherence,of detuning parameter and of transition photon number on the field entropy have been discussed.The evolution of the field entropy in the vacuum-state multiphoton J-C model iscompared with those in the themal and the coherent light field J-C models.
