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…
Higher-order Topological Type-II Hyperbolic Lattices
Liren Chen, Jingming Chen, Zhen Gao
Recently, higher-order topological phases have been extended from Euclidean lattices to non-Euclidean hyperbolic lattices. Though higher-order topological type-I hyperbolic lattice…
Spatiotemporal topological phase transitions in photonic spacetime crystals
Zebin Zhu, Bolun Huang, Siqi Xu +5
Topological phase transitions have played a central role in topological physics. However, such transitions have so far been restricted to spatial or temporal crystals. Here, we tra…
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 as…
Realization of Topology-controlled Photonic Cavities in a Valley Photonic Crystal
Bei Yan, Baoliang Liao, Fulong Shi +11
We report an experimental realization of a new type of topology-controlled photonic cavities in valley photonic crystals by adopting judiciously oriented mirrors to localize the va…
Realization of a three-dimensional photonic higher-order topological insulator
Ziyao Wang, Yan Meng, Bei Yan +13
The discovery of photonic higher-order topological insulators (HOTIs) has significantly expanded our understanding of band topology and provided unprecedented lower-dimensional top…
