“…Strikingly, although density and temperature profiles, as well as pressures, all depend strongly on N , see Figs macroscopically and thus obeys locally the thermodynamic EoS, and the boundary layers near the thermal walls, which sum up all sorts of artificial finite-size and boundary corrections to renormalize the effective boundary conditions on the remaining bulk. This remarkable bulk-boundary decoupling phenomenon, instrumental in the recent discovery of novel scaling laws in nonequilibrium fluids [46,47], is even more surprising at the light of the long range correlations present in nonequilibrium fluids [4,17,18], offering a tantalizing method to obtain macroscopic properties of nonequilibrium fluids without resorting to unreliable finite-size scaling extrapolations [47]. For comparison, we include in Fig.…”
