摘要/Abstract

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.

关键词: 光子阻塞, 关联函数, 反聚束效应, J-C模型

Abstract: The dressed states of the single atom-cavity system were described and Hilbert space was truncated t-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.

Key words: photon blockade, correlation function, anti-bunching effect, J-C model
