Emergence of hydrodynamic spatial long-range correlations in nonequilibrium many-body systems
Benjamin Doyon, Gabriele Perfetto, Tomohiro Sasamoto +1
At large scales of space and time, the nonequilibrium dynamics of local observables in extensive many-body systems is well described by hydrodynamics. At the Euler scale, one assum…
