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…
