Nonequilibrium fluctuations in time-dependent diffusion processes

A fluctuating hydrodynamics approach is presented for the calculation of the structure factor for imedependentnonequilibrium diffusive processes in binary liquid mixtures. The hydrodynamic equations

Fractional fluctuation effects on the light scattered by a viscoelastic suspension.

Fl fluctuating hydrodynamics is generalized to study the effect of fractional time derivatives on the light-scattering spectrum of a suspension in a viscoelastic solvent under an external density gradient, and it is found that the ratio of the former to the latter may be positive and up to two orders of magnitude for both types of vis coelasticity.

Enhancement of diffusive transport by non-equilibrium thermal fluctuations

We study the contribution of advection by thermal velocity fluctuations to the effective diffusion coefficient in a mixture of two identical fluids. The steady-state diffusive flux in a finite system

Slowing-down of non-equilibrium concentration fluctuations in confinement

Fluctuations in a fluid are strongly affected by the presence of a macroscopic gradient making them long-ranged and enhancing their amplitude. While small-scale fluctuations exhibit diffusive

Finite-size effects with rigid boundaries on nonequilibrium fluctuations in a liquid

In a recent publication [Physica A 291, 113 (2001)] the static structure factor of a liquid in a thermal nonequilibrium state was calculated exactly from the random Boussinesq equations, in the

A light scattering study of non equilibrium fluctuations in liquid mixtures to measure the Soret and mass diffusion coefficient.

Comparing the results with literature data, good agreement is found confirming that the proposed experimental technique can be considered a sound approach for the study of thermodiffusion processes.

On the Physical Origin of Long-Ranged Fluctuations in Fluids in Thermal Nonequilibrium States

Thermodynamic fluctuations in systems that are in nonequilibrium steady states are always spatially long ranged, in contrast to fluctuations in thermodynamic equilibrium. In the present paper we
