论文摘要
我们研究了极性phonon混合激发激发，其中描述了发射器 - 光子极化子和振动性声子的集体激发，并在与波导光子相互作用的振动两级发射器的周期性阵列中。我们证明了由声子散射与波导介导的远距离耦合之间的相互作用引起的相互作用诱导的准碘结构的出现。这种准静脉的性质从根本上改变了次级政权的激发特征，后者具有拓扑边缘状态的外观和麦古迪和多重型激发之间的过渡。还提出了一个可能的实现，该实现还提出了一系列被困在光学纳米纤维附近的激光冷却原子。我们的结果表明，在使用波导量子量子电动力学系统探索多体物理学时，将振动用作新型的自由度的可能性。
We investigate polariton-phonon hybrid excitations, which describe the collective excitations of emitter-photon polaritons and vibrational phonons, in a periodic array of vibrating two-level emitters interacting with waveguide photons. We demonstrate the emergence of an interaction-induced quasiperiodic structure caused by the interplay between phonon scatterings and waveguide-mediated long-range couplings. This quasiperiodicity fundamentally changes the excitation characteristics in the subradiant regime, which feature an appearance of topological edge states and a transition between ergodic and multifractal excitations. A possible realization consisting of an array of laser-cooled atoms trapped near an optical nanofiber is also proposed. Our results demonstrate the possibility of utilizing vibrations as a novel degree of freedom in the exploration of many-body physics with waveguide quantum electrodynamics systems.
