Description
We introduce the concept of twin phases for a symmetry S, defined as inequivalent phases, whose order parameters are part of the same generalized charge under S. Stable, direct transitions between such twin phases are never spontaneous-symmetry-breaking transitions, even after (partially) gauging the initial symmetry S: they are phase transitions without hidden symmetry breaking. We illustrate this with an (anomalous) finite group symmetry in 1+1d, which exhibits such intrinsically beyond Landau DQCP transitions.
This is based on work with Alison Warman and Yuhan Gai.
