Gapped phases and the SymTFT
byLea Bottini
Abstract:The symmetry topological field theory (SymTFT) has emerged in the past years as a powerful framework for analyzing generalized symmetries. In this talk, I will review how we can use it to characterize the gapped infrared phases of two-dimensional quantum field theories with an internal symmetry, described in general by a fusion category. I will then discuss extensions of this framework that incorporate space-time symmetries, with a particular focus on time-reversal.
