Entropy exchange and entanglement of a moving atom with k-photon Jaynes-Cummings model
k光子Jaynes-Cummings模型与运动原子相互作用中的熵交换及纠缠

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.
