研究了k光子Jaynes-Cummings模型光场的熵压缩,讨论了光子数k和原子的初始状态对光场熵压缩的影响.结果表明,随光子数k的增大,光场的位置熵压缩愈趋明显,动量熵压缩量减小;当k≥3时,位置熵始终是被压缩的.原子的初态对光场的熵压缩也有一定的影响.
We investigated the field entropy squeezing of k-photon Jaynes-Cummings model, discuss the influence of the photon number k and the initial state of the atom on the entropy squeezing. The results show that with the photon number k increasing, the position entropy squeezing will be enhanced and the momentum entropy squeezing reduced. When k ≥3, the position entropy is always squeezed. The initial state of the atom also shows some influence on the entropy squeezing.
