Generalized Symmetry in Dynamical Gravity

Explore fundamental concepts of quantum field theory and gravity in this physics seminar presented by Caltech's Clifford Cheung at NYU Physics. Delve into the expanding understanding of symmetry in quantum field theory over the past decade, with particular focus on higher-form symmetry and its action on extended objects. Learn how one-form symmetry operates within the effective field theory framework of dynamical, nonlinear gravity, drawing parallels with gauge theory. Examine the geometric interpretation of the relationship between line operators and symmetry defect operators in gravity through the lens of classical general relativity.
