| Abstract: |
In this talk, we characterize RG flows from UV fixed point described by a 2d CFT perturbed by one of its relevant operators. The first part focuses on rational CFTs. By matching the anomalies associated to their non-invertible symmetries, one conjectures infinitely many new RG flows between Minimal models of Virasoro, Wn algebras, and more general coset models. The second part presents a construction of a class of non-topological, but conserved operators in deformed CFT given by perturbed Verlinde lines. These generalize the category of topological defects in a very non trivial way and put strong constraints of the dynamics of QFTs. In the case of the minimal models, they provide infinite families of commuting non-local conserved charges associated to the new flows. This is based on work with Runkel, Watts, Konechny, as well as Prochazka and Negro. |
