我们研究了一个腔量子电动力学系统的双光子效应，其中波导耦合到嵌入在两能级系统中的腔。利用Lehmann-Symanzik-Zimmermann约简精确求解了双光子散射的波函数。我们关于出射光子的量子统计特性的结果明确地显示了强耦合状态下的光子封锁效应。这些结果与最近的实验结果一致。
We study two-photon effects for a cavity quantum electrodynamics system where a waveguide is coupled to a cavity embedded in a two-level system. The wave function of two-photon scattering is exactly solved by using the Lehmann-Symanzik-Zimmermann reduction. Our results about quantum statistical properties of the outgoing photons explicitly exhibit the photon blockade effects in the strong-coupling regime. These results agree with the observations of recent experiments.
