Global Aspects of Exactly Marginal Current-Current Deformations

Explore a 49-minute physics lecture from the Workshop on Symmetries and Gravity where MIT researcher Ho Tat Lam delves into the mathematical foundations of conformal manifolds and current-current deformations in two-dimensional field theories. Learn how discrete gauging connects different points on conformal manifolds, and understand the relationship between manifold topology and current anomalies. Discover how enhanced invertible symmetries transform into non-invertible symmetries away from symmetry enhanced points, and examine current-current deformation through the lens of continuous abelian symmetry topological field theory.
