| 摘 要： | 利用量子理论,研究了运动依赖强度耦合J-C模型的场熵的动力学特性,讨论了原子相干性、原子运动和场模结构参量对场熵演化的影响.研究结果表明,场熵大小与运动原子在能级上的初始分布和场模结构参量大小有关;场熵的演化周期随着场模结构参量的增大或原子运动速度的增大而缩短.

| Abstract: | The dynamical properties of the field entropy evolution in the intensity-dependent coupling J-C model with atomic motion are studied by means of quantum theory.The influence of atomic coherence,the atomic motion and the field-model structure on the evolution of the field is examined.The results show that the original distribution of the moving atom at energy levels and the field-mode structure parameter have an important influence on the field entropy,an increase of field-mode structure parameter or an increase of atomic speed shortens the evolution period of the entropy. |

| Keywords: | intensity-dependent coupling moving atom field entropy evolution atomic coherence field-mode structure parameter |
