Slow Thermalisation but Fast Transport - The U(1) Lattice Gauge Theory as a Unique Paradigm of Ergodicity Breaking

Explore the fascinating dynamics of U(1) lattice gauge theory through this conference talk that examines the unique phenomenon where thermalization occurs slowly while transport remains fast, presenting a distinctive paradigm of ergodicity breaking. Delve into the theoretical foundations and implications of this quantum many-body system where conventional expectations about the relationship between thermalization and transport are challenged. Learn how gauge symmetries create constraints that lead to this unusual behavior, where the system exhibits rapid transport properties despite taking extended time to reach thermal equilibrium. Discover the mathematical framework underlying these dynamics and understand how this model serves as a crucial example in the study of quantum many-body systems that violate standard thermalization assumptions. Gain insights into the broader implications for understanding ergodicity breaking in constrained quantum systems and how gauge theories provide unique platforms for studying non-equilibrium quantum dynamics.
