Fluctuating hydrodynamics of non-equilibrium interacting many-body systems — •Felipe Pereira-Alves and Aljaž Godec — Mathematical Physics and Stochastic Dynamics, Institute of Physics, University of Freiburg (GER)

Extending fluctuating hydrodynamics to non-equilibrium systems remains a significant theoretical challenge. In this work we investigate, on the level of distribution-valued fluctuating hydrodynamics, general short-range interacting systems as well as the long-range interacting Dyson process evolving from deterministic non-equilibrium initial conditions. We characterize the probability measure of the distribution-valued fluctuation field during the relaxation to equilibrium and illustrate the results on the example of discretely (in space) observed fluctuation field and compare the results to particle-resolved simulations.
