摘要:

在我们最近的文章[1]中,我们报道了与光腔强耦合的单原子光子阻塞的观测结果。为了支持这些测量,我们在这里提供了一个扩展的讨论,光子封锁的一般现象,以及在参考文献[1]中提出的理论模型和结果。我们用光子数态的透射系数描述了光子阻塞的一般条件。对于文献[1]中的原子-腔系统,我们给出了模型哈密顿量,并研究了本征值与预言的强度关联函数之间的关系。我们探讨了不同的驱动机制对光子统计的影响。我们还提出了额外的修正模型来描述腔的双折射和交流斯塔克位移。[1]K.

英文摘要:

In our recent paper [1], we reported observations of photon blockade by one atom strongly coupled to an optical cavity. In support of these measurements, here we provide an expanded discussion of the general phenomenology of photon blockade as well as of the theoretical model and results that were presented in Ref. [1]. We describe the general condition for photon blockade in terms of the transmission coefficients for photon number states. For the atom-cavity system of Ref. [1], we present the model Hamiltonian and examine the relationship of the eigenvalues to the predicted intensity correlation function. We explore the effect of different driving mechanisms on the photon statistics. We also present additional corrections to the model to describe cavity birefringence and ac-Stark shifts. [1] K. M.
