Overview:

Our understanding of universal phenomena in interacting many-body systems ranging from subatomic to  astronomical scales relies largely on the hydrodynamic framework. In the past few years, hydrodynamics has become a central theme of quantum condensed matter, soft matter (in the form of non-equilibrium active fluids), high-energy physics, and quantuminformation. Particularly significant advances have been: 1) the discovery of new effects in the hydrodynamics of quantum Hall fluids such as Hall viscosity, 2) theoretical and experimental advances in realizing the hydrodynamicregime of strongly interacting electron fluids in Graphene, GaAs, and Delafossites, and 3) the experimental realization of quantum inspired non-equilibrium chiral active fluids. These developments have been stimulated by the cross-fertilization of ideas in small inter-disciplinaryworkshops. The proposed CUNY workshop continues in this tradition and aims to bring together a group of creative experts, young and old, to synthesize these insights from disparate fields and push the frontierof quantum hydrodynamics. The topics to be covered fall in three broad categories: (1) Higher-gradient hydrodynamic effects in chiral matter,  both  classical  and  quantum,  such  as  the  Hall  viscosity  and  odd  elasticity,  as  well  as nonequilibrium  field-theoretic  approaches  to  deriving  hydrodynamics;  (2)  Recent  experimental developments in realizing the hydrodynamic regime of electron fluids; and (3) The hydrodynamics of active matter and its relevance to quantum systems.
