Under some conditions the static density correlation function becomes long ranged. We then analyze this behavior in the framework of nonequilibrium fluctuating hydrodynamics.6 p.application/pdfeng(c) American Physical Society, 1994Física estadísticaTermodinàmicaStatistical physicsThermodynamicsLong-range correlations in diffusive systems away from equilibriuminfo:eu-repo/semantics/article82432info:eu-repo/semantics/openAccess
