论文摘要
我们在有限的周期性阵列的两级原子与波导的有限周期性阵列中提供了第一个分类。我们专注于强大的次波长极限，并在复杂平面中显示本征态的层次结构。使用纠缠熵作为区别特征，探索了主要特征特征状态。我们表明，在两光子系统中发现的秩序，混乱到本地化的丰富效果相互作用自然扩展到三光子系统。还存在相互作用诱导的局部状态，这些状态是三光子系统所独有的，例如绑定的三聚体，角状状态和三聚体边缘状态。
We provide the first classification of three-photon eigenstates in a finite periodic array of two-level atoms coupled to a waveguide. We focus on the strongly subwavelength limit and show the hierarchical structure of the eigenstates in the complex plane. The main characteristic eigenstates are explored using entanglement entropy as a distinguishing feature. We show that the rich interplay of effects from order, chaos to localisation found in two-photon systems extends naturally to three-photon systems. There also exist interaction-induced localised states unique to three-photon systems such as bound trimers, corner states and trimer edge states.
