abstract
We propose an effective action for first order relativistic dissipative hydrodynamics that can be used to evaluate n-point symmetrized correlation functions, taking into account thermal fluctuations of the hydrodynamic variables.

In Bjorken flow, non-Gaussian velocity fluctuations evolve with nonlinear coupling between two- and three-point correlators and memory effects, best analyzed in the average Landau frame which coincides with the density frame.

Schwinger-Keldysh effective theory of charge transport: redundancies and systematic $\omega/T$ expansion
Proves equivalence of redundant Goldstone and adjoint-matter formulations of SK EFTs for non-Abelian symmetries and extends both to all orders in ħω/T while classifying invariant kernels under DKMS and unitarity.
