Hydrodynamics of kinematically constrained fluids.
I will introduce a zoo of new hydrodynamic universality classes, which describe the thermalization of interacting systems subject to kinematic constraints: for example, a theory where the center of mass must be exactly conserved. I will show that this simple added constraint leads to a wealth of new phenomena, including subdiffusive relaxation of charge, and (in the presence of either time-reversal symmetry breaking or momentum conservation) the breakdown of hydrodynamics itself! I will highlight both numerical and actual experimental realizations of our theoretical predictions, as well as sketch how we are generalizing effective field theory to these dissipative (and usually non-thermal) systems.
