TL;DR
This paper investigates how density fluctuations in diffusive systems far from equilibrium can develop long-range correlations, analyzed through nonequilibrium fluctuating hydrodynamics.
Contribution
It provides a theoretical framework explaining the emergence of long-range correlations in nonequilibrium diffusive systems.
Findings
Static density correlation functions become long-ranged under certain conditions.
The behavior is analyzed using nonequilibrium fluctuating hydrodynamics.
Long-range correlations are linked to nonequilibrium conditions.
Abstract
We study the dynamics of density fluctuations in purely diffusive systems away from equilibrium. Under some conditions the static density correlation function becomes long-ranged. We then analyze this behavior in the framework of nonequilibrium fluctuating hydrodynamics.
