We study the propagation of strongly interacting Rydberg polaritons through an atomic medium in a one-dimensional optical lattice. We derive an effective single-band Hubbard model to describe the dynamics of the dark-state polaritons under realistic assumptions. Within this model, we analyze the driven-dissipative transport of polaritons through the system by considering a coherent drive on one side and by including the spontaneous emission of the metastable Rydberg state. Using a variational approach to solve the many-body problem, we find strong antibunching of the outgoing photons despite the losses from the Rydberg state decay.
我们研究了强相互作用里德堡极化激元在一维光学晶格中的原子介质中的传播。我们推导了一个有效的单带哈伯德模型，以描述在现实假设下暗态极化激元的动力学。在这个模型中，我们通过考虑一侧的相干驱动并包括亚稳态里德堡态的自发辐射，来分析极化激元在系统中的驱动耗散输运。使用变分方法来解决多体问题，我们发现尽管有来自里德堡态衰变的损耗，但出射光子仍有强烈的反聚束现象。
