Topological electronic structure and spin texture of quasi-one-dimensional higher-order topological insulator Bi4Br4
Abstract The notion of topological insulators (TIs), characterized by an insulating bulk and conducting topological surface states, can be extended to higher-order topological insulators (HOTIs) hosting gapless modes localized at the boundaries of two or more dimensions lower than the insulating bul...
