摘要: 基于 Su-Shrieffer-Heeger(SSH)模型, 利用截断维格纳近似(TWA)研究了开放拓扑波导的稳态性质。 研究表明,通过将拓扑波导的每个腔加上相同的驱动和耗散,在系统达到稳态时,拓扑波导的光子分布会出现趋于边缘和趋于次边缘两种不同的趋肤效应。随二聚参数的增大,趋肤效应从趋于边缘变为趋于次边缘,最终逐渐消失。 本工作将为在量子开放系统中研究多体系统的拓扑性质提供新的思路。

Abstract: Based on the Su-Schrieffer-Heeger (SSH) model, the steady-state properties of an open topological waveguide were investigated using the truncated Wigner approximation (TWA). The study demonstrates that by applying identical drive and dissipation to each cavity in the topological waveguide, two distinct skin effects emerge in the photon distribution upon reaching steady state: localization toward the edges and localization toward the sub-edges. As the dimerization parameter increases, the skin effect shifts from edge localization to sub-edge localization, eventually diminishing completely. This work offers new insights for exploring topological properties of many-body systems in open quantum systems.
