摘要
利用全量子理论 ,研究了非旋波近似下两个二能级原子与单模光场相互作用过程中光场所表现出的非经典性质 ,揭示了虚光子过程对场的平均光子数和二阶相干度的影响 。
In this paper, the nonclassical properties of two two-level atoms interacting with a single mode light field is studied by means of the quantum theory without rotating wave approximation. The influences of the virtual photon process on the mean photon number and the degree of second order coherence of field are also discussed. The relations between the field frequency, the coupling constants of two atoms and the mean photon number, the degree of second order coherence of field are revealed.
