From: Identifying topological phases through global and local symmetries of the quantum transfer matrix
Phase diagram of the filtered TC. (a) The phase diagram is constructed exclusively based on the interplay between local and global symmetries. It highlights three phases with distinct breaking patterns of the global \({\varvec{g}}_{ZZ} \times {\varvec{g}}_{ZI}\) symmetries, along with two symmetry-enriched Ising CFT lines that separate them. (b) The phase diagram is enhanced by the inclusion of additional information regarding the global symmetry present along the dashed curve. At a point on this curve, the two distinct Ising CFTs merge into the \((\textrm{Ising})^2\) CFT with \(c=1\).
