报告摘要：

拓扑光子学成功地为光子操纵开辟了一个新的自由度，这引起了人们对非厄米物理的极大兴趣。在本次报告中，我将介绍我们最近在利用集成光子波导晶格中的非厄米性操纵拓扑态(零能模式，异常Floquet模式，Weyl界面模式和趋肤模式)方面的努力。我还将展示凝聚态和粒子物理的基本概念(人工规范场和超对称)如何促进片上集成光子器件的设计。

Abstract:

Topological photonics has successfully opened up a new degree of freedom for light manipulations, which has sparked considerable interest in connection with non-Hermitian physics. In this talk, I will discuss our recent efforts in manipulating the topological states (zero mode, anomalous Floquet mode, Weyl interface mode, and skin mode) via non-Hermiticity in integrated photonic waveguide lattices. I will also show how fundamental concepts in condensed matter and particle physics (artificial gauge field and supersymmetry) facilitate the design of on-chip integrated photonic devices.
