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…
Space and space-time topologies in a type-II hyperbolic lattice
Jingming Chen, Zebin Zhu, Minqi Cheng +3
Recent breakthroughs in hyperbolic lattices have expanded the study of topological phases of matter from Euclidean to non-Euclidean spaces. However, prior work has mostly focused o…
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…
Dynamic Transfer of Chiral Edge States in Topological Type-II Hyperbolic Lattices
Jingming Chen, Linyun Yang, Zhen Gao
The discovery of hyperbolic lattice, a discretized regularization of non-Euclidean space with constant negative curvature, has provided an unprecedented platform to extend topologi…
Topological Dirac-vortex modes in a three-dimensional photonic topological insulator
Bei Yan, Yingfeng Qi, Ziyao Wang +8
Recently, topological Dirac-vortex modes in Kekulé-distorted photonic lattices have attracted broad interest and exhibited promising applications in robust photonic devices such a…
