Hypergroup Symmetry in Relative Quantum Field Theories and Chiral Algebras
Terry Gannon, Brandon C. Rayhaun
A QFT is said to be relative if it lives at the boundary of a topological QFT in one higher dimension. We develop a general framework for working with noninvertible symmetries of r…

Defect Anomalies, a Spin-Flux Duality, and Boson-Kondo Problems
Zohar Komargodski, Fedor K. Popov, Brandon C. Rayhaun
We show that the infrared phases of certain line defects in 2+1d quantum field theories are determined by anomalies, including anomalies in the space of defect coupling constants,…
