We propose a hybrid quantum system where the strong coupling regime can be achieved between a Rydberg atomic ensemble and propagating surface phonon polaritons on a piezoelectric superlattice. By exploiting the large electric dipole moment and long lifetime of Rydberg atoms as well as tightly confined surface phonon polariton modes, it is possible to achieve a coupling constant far exceeding the relevant decay rates. The frequency of the surface mode can be selected so that it is resonant with a Rydberg transition by engineering the piezoelectric superlattice. We describe a way to observe the Rabi splitting associated with the strong coupling regime under realistic experimental conditions. The system can be viewed as a new type of optomechanical system.
我们提出了一种混合量子系统，其中里德堡原子系综与压电超晶格上传播的表面声子极化激元之间可以实现强耦合 regime。通过利用里德堡原子的大电偶极矩和长寿命以及紧密受限的表面声子极化激元模式，有可能实现一个远远超过相关衰减率的耦合常数。通过设计压电超晶格，可以选择表面模式的频率，使其与里德堡跃迁共振。我们描述了一种在实际实验条件下观察与强耦合 regime 相关的拉比分裂的方法。该系统可被视为一种新型的光机械系统。
