Non-onsiteable, Not Gaugeable Symmetries with Trivially Symmetric Product States

This conference talk by Carolyn Zhang from Harvard, titled "Non-onsiteable, not gaugeable symmetries with trivially symmetric (product) states," was recorded as part of the Generalized Symmetries: High-Energy, Condensed Matter and Mathematics KITP conference held from April 7-10, 2025 at the Kavli Institute for Theoretical Physics at UC Santa Barbara. Explore cutting-edge research in quantum field theory focusing on how symmetries can be interpreted through topological defects acting on operator spaces. The 46-minute presentation contributes to a decade of progress in generalizing symmetry concepts using Lagrangian field theory techniques, revealing significant implications for condensed matter, high energy physics, and quantum gravity. Coordinated by experts Maissam Barkeshli, Michele Del Zotto, Sakura Schafer-Nameki, and Shu-Heng Shao, this talk is part of a conference designed to help participants understand recent advances and open problems in the field.
