Fluctuations of a flux driven interface

Research output: Contribution to journalArticlepeer-review

We investigate a low temperature lattice gas with short range attractive forces. Boundary chemical potentials are imposed in such a way that a sharp interface separates low and high density domains and such that there is a constant mass flux perpendicular to this interface. From a continuum theory (fluctuating hydrodynamics) we determine the interface fluctuations in this nonequilibrium steady state. They turn out to be reduced as compared to thermal equilibrium.
