摘　　要：文章研究了k光子Jaynes-Cummings模型与运动原子相互作用中的熵相互关系及纠缠特性.发现原子与光场之间具有熵交换特性.讨论了原子运动、光子数k和场模结构等因素对原子与光场熵相互关系的影响.此外,讨论了原子与场系统熵交换与纠缠之间的关系.The entropy correlation and the entanglement of a moving atom interacting with k-photon Jaynes-Cummings model are investigated.Entropy exchange between atomic and field subsystems,which is a form of anti-correlated behavior,is explored.Analytical results show that atomic motion,transition number k of field and field-mode structure can influence the entropy exchange between atom and light field.Moreover,the relationship between entropy correlations and entanglement is also discussed.
