依赖强度耦合的J—C模型原子发射功率谱密度

Atomic Emmission Power Spectra of the intensity-Dependent Coupling Jaynes-Cummings Model

本文研究了依赖强度耦合的Ｊ－Ｃ模型原子发射功率谱密度，分析了初始光场数态、相干态、压缩真空态中叠加态原子的发射谱特性。结果发现，该模型的单光子发射谱不同于通常的Ｊ－Ｃ模型，在光谱探测器的通带宽度较小的情况下，光子数很大的数态光场中其激发态原子的发射谱仍呈现四峰结构；而一般的叠加态原子的发射谱为六峰结构。

We have investigated the atomic edrission power Bpectra of a Jaynes-Cummings model with intensity-dependent coupling with a radiation field initially assumed in the number state, coherent state,squeezed vacuum state and the two-level atom prepared in a coherently superposition state. It is shown that in contrast with the results obtained in a usual one-photon JCM the atomic emmission power spectra,mearsured by the spectrometer with small bandwidth, for the atom initiajly excited state in the number state field with large photon number remains a four-peak structures but for the atom initially coherentlysuperposition state it exhibits a six-peak structures.
