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.
Lectures summarizing the construction of hydrodynamic EFTs through strong-to-weak symmetry breaking, with examples from spin chains to relativistic QFTs and UV/IR constraints on transport coefficients.
