多光子Jaynes-Cummings模型中与Glauber-Lachs态相互作用原子的熵压缩
Entropy squeezing of a multiphoton Jaynes-Cummings atom with the Glauber-Lachs state
摘要
Abstract
The information entropy squeezing properties of the atom interacting with the Glauber-Lachs state in multi-photon Jaynes-Cummings model are studied by means of the full quantum theory.The in-fluences of the mean number of the coherent photons,the average number of the thermal photons,the number of the transition photons and the atomic initial state on the information entropy squeezing of the atom are discussed.The results indicate that there is no entropy squeezing in the X component of infor-mation entropy of the atom at any instant of the time evolution of the system.But there exists an entro-py squeezing in the Y component of information entropy of the atom during the time evolution when the mean number of coherent photons takes an appropriate value.The mean number of thermal photons and the number of the transition photons have a destructive effect on theY component of information entropy of the atom.The atomic initial state has no effect on the entropy squeezing in the Y component of infor-mation entropy of the atom.If the number of the transition photons equals to two,the time evolution of the entropy squeezing factor appears periodic change.关键词
