Abstract
Over the past few years tremendous progress has been made in our understanding of quantum theories by interpreting symmetries in terms of topological operators. This had led to a generalization of the notion symmetry whereby operators are organized into higher algebraic structures. Prime examples of theories with generalized (categorical) symmetries are obtained by gauging finite group symmetries. In this talk I will present recent progress to realize such symmetry operators together with the corresponding duality operators in quantum lattice models. The corresponding (higher) categorical charges as well as the fate of topological sectors under dualities will also be discussed.
