The Navier-Stokes Equations from a Minimal Effective Field Theory

Authors: Matthew Stephenson

We use an effective Schwinger-Keldysh field theory of long-range massless modes to derive the Navier-Stokes equations as an energy-momentum balance equation. The fluid will be invariant under the linear subgroup of the volume-preserving diffeomorphisms, which are the non-linear, time-independent spatial translations.
