Abstract:

We study possible phases and possible continuous phase transitions in 1+1D systems with a given finite symmetry. We use the corresponding categorical symmetry and its condensable algebras to classify the possible gapped phases and possible gapless critical points, as well as determine the CFT of the critical points.
