Unconventional topological edge states in one-dimensional gapless systems stemming from nonisolated hypersurface singularities
Hongwei Jia, Jing Hu, Ruo-Yang Zhang +7
Topologically protected edge states have been extensively studied in systems characterized by the topological invariants in band gaps (also called line gaps). In this study, we unv…

Three-dimensional non-reciprocal transport in photonic topological heterostructure of arbitrary shape
Mudi Wang, Ruo-Yang Zhang, Chenyu Zhang +6
Electromagnetic wave propagation in three-dimensional space typically suffers omnidirectional scattering when encountering obstacles. In this study, we employed Chern vectors to co…
