A Gapless Phase with Haagerup Symmetry
Lea E. Bottini, Sakura Schafer-Nameki
We construct a (1+1)d gapless theory which has Haagerup symmetry. The construction relies on the recent exploration of the categorical Landau paradigm applied to fu…

The Club Sandwich: Gapless Phases and Phase Transitions with Non-Invertible Symmetries
Lakshya Bhardwaj, Lea E. Bottini, Daniel Pajer +1
We provide a generalization of the Symmetry Topological Field Theory (SymTFT) framework to characterize phase transitions and gapless phases with categorical symmetries. The centra…

Gapped Phases with Non-Invertible Symmetries: (1+1)d
Lakshya Bhardwaj, Lea E. Bottini, Daniel Pajer +1
We propose a general framework to characterize gapped infra-red (IR) phases of theories with non-invertible (or categorical) symmetries. In this paper we focus on (1+1)d gapped pha…
