研究了两个非相互作用的两级发射器的集体动力学，它们耦合到支持双光子束缚态的结构化波导。调整两个发射器的能量，使它们与双光子束缚态能带共振，我们确定了系统显示分数布居和基本上无阻尼的拉比振荡的参数范围。拉比振荡在单发射极动力学中没有类似物，归因于发射极-光子耦合引起的集体极化子状光子态的存在。完整的动力学由二态模型再现，其中光子极化子与态 | 相互作用。 e、e、vac i（处于激发态和空波导的两个发射器）通过取决于发射器间隔的拉比耦合频率。我们的工作表明，发射体-光子耦合可以导致双光子束缚态和可调谐非马尔可夫动力学之间的全面动量空间相互作用，为耦合到波导的发射体阵列开辟了新的方向。
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, vac i (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.
