Theory of robust ergodicity breaking in quantum many-body systems with long-range interactions Alessio Lerose (University of Oxford) Recent years have seen the discovery of a number of routes to (strong or weak forms of) ergodicity breaking in isolated quantum many-body systems, even in absence of quenched disorder. Quantum many-body scars (QMBS) – exceptional energy eigenstates […]

Eigenoperator thermalization Berislav Buca (Niels Bohr Institute) **Online seminar** I will provide a framework for computing time-averaged dynamics in locally interacting systems in any dimension. It is based on pseudolocal dynamical symmetries generalising pseudolocal charges and unifies seemingly disparate manifestations of quantum non-ergodic dynamics including quantum many-body scars, continuous, discrete and dissipative time crystals, Hilbert

When poor little fish are confronted with AI, robot-fish, virtual reality, and drones Clément Sire (LPT Toulouse) After introducing the collective behaviors observed in fish schools, I will outline a methodology for quantitatively measuring social interactions (attraction/repulsion; alignment) within animal groups. The reconstructed interactions can then be directly implemented in analytical models which quantitatively reproduce
