Many-Body Quantum Chaos and Quantum Thermodynamics

Understanding and justifying the emergence of equilibrium behavior in generic, non-integrable many-body quantum systems is a longstanding challenge at the very heart of statistical mechanics. We are exploring how concepts and tools from quantum information theory may be used to build a consistent theoretical framework for describing ergodicity and mixing properties in many-body quantum systems that lack a natural classical counterpart, and to characterize distinctive aspects of complex quantum dynamics. Beside their foundational implications, these studies are directly relevant to ongoing experiments on quantum chaos and thermalization dynamics in Ramanathan's group.
