Phases with Non-Invertible Symmetries in (1+1)d: From Categories to Cold Atoms

This 38-minute conference talk titled "Phases with Non-Invertible Symmetries in (1+1)d: From Categories to Cold Atoms" features Alison Warman from Oxford University presenting at the Generalized Symmetries conference held at the Kavli Institute for Theoretical Physics (KITP) at UC Santa Barbara. Explore how quantum field theory has advanced through interpreting symmetries as topological defects acting on operator spaces, leading to a generalized understanding of symmetries with applications in condensed matter, high energy physics, and quantum gravity. The talk is part of a broader conference bringing together experts to discuss recent advances and open problems in the field of generalized symmetries. Coordinated by Maissam Barkeshli, Michele Del Zotto, Sakura Schafer-Nameki, and Shu-Heng Shao, this presentation contributes to the ongoing dialogue about the rich landscape of physical effects discovered through Lagrangian field theory techniques.
