Explore Fock space fragmentation phenomena in quantum quench dynamics of disordered interacting fermionic systems through this 46-minute conference talk. Delve into the theoretical framework of quantum many-body dynamics where disorder and interactions compete to create fragmented Hilbert spaces that violate conventional thermalization expectations. Learn how quantum quenches in these systems lead to non-ergodic behavior and the emergence of distinct dynamical phases characterized by incomplete exploration of the available phase space. Examine the mathematical formalism describing how initial states become trapped in disconnected sectors of Fock space, preventing full thermalization and creating persistent memory of initial conditions. Understand the implications for quantum simulation experiments and the broader context of thermalization violations in many-body quantum systems. Gain insights into cutting-edge research connecting condensed matter theory, quantum statistical mechanics, and the fundamental principles governing equilibration in isolated quantum systems.
