Title: U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography

Abstract: In nature symmetries are softly broken in a wide range of systems, from axial charge relaxation in QCD to pinned charge density wave states in condensed matter. As a toy model for more realistic situations, in this talk I will study the low energy physics of a system with an approximate U(1) global symmetry, using effective field theory and holographic methods. I will begin by discussing the construction of Schwinger-Keldysh effective hydrodynamic actions, and I will apply these techniques in the case of hydrodynamics with U(1) charge relaxation. I will then explain how one can derive this SK effective action by performing a holographic analysis of a bulk Proca model.
