Antichiral hinge states in a higher-order photonic nodal ring semimetal
Yuchen Peng, Deep Mondal, Yuting Yang +17
Antichiral states propagate in the same direction on opposite boundaries, defying the conventional constraint that boundary modes must cancel net chirality. Previously found antich…
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…
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 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…
