A Non-Abelian Route to Z2 Non-Hermitian Skin Effects
Huiyan Tang, Yaxuan Zhang, Ziteng Wang +7
The non-Hermitian skin effect (NHSE), characterized by extensive boundary accumulation of eigenstates under open boundary conditions, has emerged as a central phenomenon in non-Her…
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…
Phase Transitions and Topological Protection in Anyonic-PT-Symmetric Lattices
Ruiying Zhang, Ziteng Wang, Daohong Song +3
Parity-time (PT) symmetry and anti-PT symmetry have attracted extensive interest for their non-Hermitian spectral properties, particularly the emergence of purely real and imaginar…
Controllable Lateral Optical Forces on Janus Particles in Fluid Media
Ziheng Xiu, Yue Chai, Pengyu Wen +7
Optical forces - studied since the earliest days of laser physics - continue to reveal rich dynamics and enable powerful tools for manipulation of objects on micro- and nanoscales,…
