Title: Hydrodynamics and collective behaviour across scales: from high-energy to gravity, quantum/active matter, and social dynamics.

 

Abstract: In recent years hydrodynamics has become a universal language for emergence, describing the collective behaviour of a wide range of systems and phases of matter. Its universality is rooted in the notions of generalised symmetries, symmetry breaking patterns and the laws of thermodynamics. I will give an overview of the applicability of hydrodynamics and recent efforts aimed at gaining insights using effective field theory to model a wide variety of systems, including the quark-gluon plasma, D-branes, black holes, accretion disks, graphene, plastics, solids, active matter and social systems with many interacting agents. I will also discuss the distinction between passive and active phases of matter and how this can help us to better understand the physics of non-equilibrium (living) systems, but will also highlight why active phases of matter are perhaps more common in the universe than currently discussed.
