SUMMARY:Emergent Non-Invertible Symmetries —The Adjoint QCD Example
DESCRIPTION:Quantum Field Theory and Physical Mathematics Seminar \nSpeaker: Shani Nadir Meynet (Uppsala) \nTitle: Emergent Non-Invertible Symmetries — The Adjoint QCD Example \nAbstract: After reviewing some general properties of generalized symmetries and the renormalization group (RG) flow for quantum field theories (QFT)\, I’ll describe how the recently discovered non-invertible symmetries can be used to study theories at strong coupling. I’ll illustrate these facts using (3+1)-dimensional adjoint QCD with two flavors as an example. This theory can be obtained by mass deforming a pure N=2 super Yang-Mills theory. Relying on supersymmetric results\, dynamical abelianization and monopole condensation\, we are able to get to the description of an infrared (IR) phase as an abelian theory flowing to a CP1 sigma model. In this scenario\, the IR phase has an emergent non-invertible symmetry\, which is matched with the non-invertible symmetry of the IR CP1 phase. This result illustrates how an emergent non-invertible symmetry can be used to provide a bridge connecting gauge theories at strong coupling and their IR via dynamical abelianization. \n
