Observation of Antichiral Hinge States in a Three-dimensional Gyromagnetic Photonic Crystal
Ziyao Wang, Tianzhi Xia, Han-Rong Xia +1
Recent advances in topological physics have revealed a counterintuitive class of antichiral edge and surface states that propagate in the same direction along spatially separated p…
Observation of biased random-flux-induced topological phase transition in gyromagnetic photonic crystals
Hai-Xiao Wang, Chongyang Li, Xianmu Wu +5
The paper experimentally demonstrates a disorder‑driven topological phase transition in gyromagnetic photonic crystals by randomly orienting the magnetization of rods, creating a b…
Observation of fractality-induced topology in photonic crystals
Bei Yan, Yingfeng Qi, Xiang Xi +6
Fractal topology--achieved by integrating nontrivial topology into fractal geometries with self-similarity and non-integer dimensions--has opened new avenues for exploring topologi…
Observation of Fully Flat Bands in a Photonic Dipolar Kagome Lattice
Han-Rong Xia, Ziyao Wang, Yunrui Wang +2
Flat bands, characterized by zero group velocity and strong energy localization, enable interaction-enhanced phenomena across both quantum and classical systems. Existing photonic…
Three-dimensional topological disclination in acoustic crystals
Zhenxiao Zhu, Yan Meng, Minmiao Wang +11
Topological disclinations, crystallographic defects that break rotation lattice symmetry, have attracted great interest and exhibited wide applications in cavities, waveguides, and…
