"Characterizing bulk properties of gapped phases by smeared boundary conformal field theories: Role of duality in unusual ordering" (cowork with Dr.Yoshiki Fukusumi) arXiv:2605.07734[hep-th]
We studied the low-energy (IR) gapped phase obtained via the massive renormalization group (RG) flow from a conformal field theory described by a certain fusion ring symmetry under assuming the presence of preserving (sub)symmetry, for the class of massive RG flow called "dual" massive flow. As a result, we checked that the gapped phase obtained by such a flow cannot be approximated by (smeared) Cardy states, contrary to previously believed conjecture.
