Operator Dynamics and Spectral Correlations in Chaotic Many-Body Systems

Explore operator dynamics and spectral correlations in chaotic many-body quantum systems through this 46-minute conference talk by J. Chalker from the University of Oxford. Delve into the theoretical framework governing how operators evolve in time within chaotic many-body systems and examine the statistical properties of energy level spacings and correlations. Learn about the connections between quantum chaos, random matrix theory, and many-body localization as Chalker discusses the emergence of universal spectral statistics in strongly interacting quantum systems. Understand how operator spreading and entanglement growth relate to spectral properties, and discover the role of effective field theories in describing non-equilibrium dynamics. Gain insights into current research directions in quantum many-body chaos, including the eigenstate thermalization hypothesis and its implications for understanding thermalization in isolated quantum systems.
