Anomalous Hydrodynamics of Low Dimensional Quantum Systems
Explore the fascinating world of quantum hydrodynamics in low-dimensional systems through this 52-minute physics colloquium talk. Delve into the recent revival of quantum hydrodynamics as an effective theory describing the evolution of many-body quantum systems from local to global equilibrium. Examine the rich phenomena in low-dimensional fluids, including transport anomalies and the proximity to integrability. Investigate the hydrodynamics of systems near integrable limits, featuring numerous approximate conservation laws and long-lived quasiparticle excitations. Learn about the breakdown of Fick's diffusion law in one-dimensional isotropic magnets, leading to anomalous "superdiffusive" transport properties. Discover recent experimental findings probing these transport anomalies and contemplate the open questions they raise in the field of quantum physics.
