Topology of Wilson-loop spectrum and periodic evolution of surface-state Fermi arc
Yi-Dong Wu
Wilson-loop has been widely used to characterize the topological property of topological insulators, high order topological insulators and topological semimetals. Both bulk topolog…

Corner states are not topologically protected
Yi-Dong Wu
Recently there is a surge of interests in the so-called topologically protected corner states in 2D and 3D systems. Such systems are considered as high order topological insulators…

Topological properties in one-dimensional periodic systems
Yi-Dong Wu
Recently there is trend to study topological properties in one-dimensional(1D) periodic systems. Concepts such as Zak phase are considered as topological invariants that characteri…
