When do anomalous finite symmetries in (3+1)d enforce gaplessness?
Quantum Field Theory and Physical Mathematics Seminar Speaker: Matthew Yu (University of Oxford) Title: When do anomalous finite symmetries in (3+1)d enforce gaplessness? Abstract: I will explain a comprehensive framework for characterizing the infrared (IR) phases of a fermionic QFTs in (3+1)d, based on their quantum anomalies associated with a finite symmetry. We uncover a […]
