Effective Theories for Hydrodynamics: discussion session
- There are no conveners in this block
Description
In these lectures we describe a first principle formulation of hydrodynamics where, to incorporate effects of dissipation and fluctuations, the Schwinger-Keldysh formalism plays a crucial role. Using an effective field theory approach we first establish what are the necessary low-energy degrees of freedom and the symmetries that a Schwinger-Keldysh effective action should have to describe hydrodynamic behaviour. Subsequently, we show how this formalism can be efficiently implemented using superspace techniques to obtain simple effective actions. Finally, we give a derivation of the local second law of thermodynamics by applying a Noether-like procedure to the effective action.
