论文摘要
研究了两个非相互作用的两级发射器的集体动力学，这些动力学与支持两光子结合状态的结构波导指南相连。调整两个发射器的能量，使它们与两光子结合的状态能带共振，我们确定了该系统显示分数种群并基本上未抑制Rabi振荡的参数状态。在单个发射极动力学中没有类似物的Rabi振荡归因于由发射极 - 光子耦合引起的集体极性光子光子状态的存在。完整的动力学是由两态模型复制的，其中光子极化子与状态$ | e，e，\ text {vac} \ rangle $（具有激发状态的两个发射器和空波指南中的两个发射器）通过拉比耦合频率取决于发射器分离。我们的工作表明，发射机 - 光子耦合可以导致两光子结合状态和可调的非马克维亚动力学之间的全部动量空间相互作用，从而为发射器阵列耦合到波导的新方向。
The collective dynamics of two non-interacting two-level emitters, which are coupled to a structured wave guide that supports two-photon bound states, is investigated. Tuning the energy of the two emitters such that they are in resonance with the two-photon bound state energy band, we identify parameter regimes where the system displays fractional populations and essentially undamped Rabi oscillations. The Rabi oscillations, which have no analog in the single-emitter dynamics, are attributed to the existence of a collective polaron-like photonic state that is induced by the emitter-photon coupling. The full dynamics is reproduced by a two-state model, in which the photonic polaron interacts with the state $|e,e,\text{vac} \rangle$ (two emitters in their excited state and empty wave guide) through a Rabi coupling frequency that depends on the emitter separation. Our work demonstrates that emitter-photon coupling can lead to an all-to-all momentum space interaction between two-photon bound states and tunable non-Markovian dynamics, opening up a new direction for emitter arrays coupled to a waveguide.
