In the first part of this talk I will describe how the formalism of non-equilibrium effective field theory (EFT) provides a field-theoretical description of the low-energy behavior of systems in local thermal equilibrium. I will then show how magnetohydrodynamics can be incorporated in this formalism using generalized global symmetries. In the second part of the talk I will discuss response for Floquet systems, which do not possess a notion of equilibrium, and for which we lack of an effective theory formulation. I will show how this can be remedied by applying the approach of non-equilibrium EFT to describe topological response of such systems.
