Anomalies of Defect Parameter Spaces and a Spin-Flux Duality

Explore how renormalization group irreversibility and anomalies constrain infrared phases of defects in quantum field theories through this high energy theory seminar. Learn about anomalies in coupling constant spaces and their applications to understanding defect behavior in familiar quantum field theories. Discover evidence for a conjectural "spin-flux duality" that describes the mapping of line operators across particle/vortex duality in 2+1 dimensional systems. Examine the theoretical framework connecting renormalization group flow, anomaly structures, and duality transformations in the context of defect quantum field theory. Gain insights into advanced techniques for analyzing defect parameter spaces and their constraints on possible infrared phases, with particular focus on the interplay between topological properties and renormalization group dynamics.
