Generalized symmetries and their application in topological phases of matter
Recently, the notion of symmetry has been generalized, including high form, subsystem, and noninvertible symmetries. These novel symmetries have extended our understanding of topological phases of matter. In this talk, I will review the recent development on generalized symmetry, with a focus on noninvertible symmetry and the phases protected by it. I will present a general method to classy a broad class of noninvertible symmetry protected topological phases (NISPTs), together with concrete lattice realizations.
