非旋波近似下两个原子与场模型中的聚束与反聚束效应

Bunching and Antibunching Effects of Two Two-Level Atoms Interacting with Light Field under the Counter-Rotating-Wave Approximation

用完全量子化方法 ,研究在非旋波近似下两个二能级原子与场相互作用过程中的聚束与反聚束效应 .揭示了光场频率的变化对场的二阶相干度的影响 。

In this paper, the bunching and antibunching effects of single mode light field in T C model is studied by means of the quantum theory .Under counter rotating wave approximation,the influences of the field frequency on the degree of second order coherence of field are also discussed. The relations between the coupling constants of two atoms ,the field strength and the degree of second order coherence of field are revealed.
