摘　　要：对单原子-腔系统进行缀饰态描述,并研究Hilbert空间的有效截断及其截断部分的双光子跃迁过程.通过求解体系的主方程,计算双光子共振跃迁导致的能级移位,并计算光子的二阶关联函数,证实在给定的参数条件下存在光子反聚束效应.The dressed states of the single atom-cavity system were described and Hilbert space was truncated to study the two-photon transition process.By solving the master equation of the system,we calculated the energy level shift caused by two-photon resonance transition,and calculated the second-order correlation function of photon,which confirmed the existence of photon anti-bunching effect under given parameters.

关 键 词：光子阻塞 关联函数 反聚束效应 J-C模型
