腔阵列中实现的扩展哈伯德模型中相互作用诱导的双光子边缘态

Interaction-induced two-photon edge states in extended Hubbard model realized in a cavity array

Maxim A. Gorlach, Alexander N. Poddubny

摘要:

本文从理论上研究了同时具有在位和非局域克尔非线性的周期耦合腔阵列中的双光子态。在没有非线性的情况下,该结构是拓扑平凡的,没有边缘状态。由扩展的哈伯德模型描述的两种非线性相互作用机制的相互作用促进了束缚光子对边缘态的形成。给出了双光子波函数的数值和精确解析结果。因此,我们的研究结果揭示了复合粒子的边缘状态及其局域化特性。

英文摘要:

We study theoretically two-photon states in a periodic array of coupled cavities with both on-site and nonlocal Kerr-type nonlinearities. In the absence of nonlinearity the structure is topologically trivial and possesses no edge states. The interplay of two nonlinear interaction mechanisms described by the extended Hubbard model facilitates formation of edge states of bound photon pairs. Numerical and exact analytical results for the two-photon wave functions are presented. Our findings thus shed light onto the edge states of composite particles and their localization properties.
