Fractal hierarchy enables exponential scaling of topological boundary states
Limin Song, Zhichan Hu, Ziteng Wang +7
Exponential growth describes an extremely rapid process ubiquitous across mathematics and diverse physical, biological, and technological systems. Here, we introduce a class of fra…
Topological photonics in one-dimensional settings
Shiqi Xia, Ziteng Wang, Domenico Bongiovanni +7
Over the past decade, topological photonics has emerged as a vibrant field, attracting significant attention and witnessing remarkable advancements. This growth can be attributed t…
Subsymmetry-protected compact edge states
Ruoqi Cheng, Domenico Bongiovanni, Ziteng Wang +6
Sub-symmetry (SubSy) protected topological states represent a concept that goes beyond the conventional framework of symmetry-protected topological (SPT) phases, demonstrating that…
Quadratic Band Touching and Nontrivial Winding Reveal Generalized Angular Momentum Conservation
Yihan Wang, Domenico Bongiovanni, Dario JukiÄ +7
Angular momentum conservation stands as one of the most fundamental and robust laws of physics. In discrete lattices, however, its realization can deviate markedly from the continu…
Multi-topological phases of matter
Ziteng Wang, Domenico Bongiovanni, Xiangdong Wang +7
The discovery of topological phases of matter and topological boundary states had tremendous impact on condensed matter physics and photonics, where topological phases are defined…
Thermalization dynamics in photonic lattices of different geometries
Guowen Yang, Domenico Bongiovanni, Daohong Song +3
The statistical mechanical behavior of weakly nonlinear multimoded optical settings is attracting increased interest during the last few years. The main purpose of this work is to…
