Generalized Casimir forces in nonequilibrium systems.

In the present work, we propose a method to determine fluctuation-induced forces in nonequilibrium systems. These forces are the analog of the well-known Casimir forces, which were originally introduced in quantum field theory and later extended to the area of critical phenomena. The procedure starts from the observation that many nonequilibrium systems exhibit fluctuations with macroscopic cor...

Thermophoresis in colloidal suspensions driven by Marangoni forces.

In a hydrodynamic approach to thermophoretic transport in colloidal suspensions, the solute velocity u and the solvent flow v(r) are derived from Stokes' equation, with slip boundary conditions imposed by thermal Marangoni forces. The resulting fluid velocity field v(r) significantly differs from that induced by an externally driven particle. We find, in particular, that thermophoresis due to s...

Depletion forces in nonequilibrium.

The concept of effective depletion forces between two fixed big colloidal particles in a bath of small particles is generalized to a nonequilibrium situation where the bath of small Brownian particles is flowing around the big particles with a prescribed velocity. In striking contrast to the equilibrium case, the nonequilibrium forces violate Newton's third law; they are nonconservative and str...

Probing interaction forces in colloidal monolayers: Inversion of structural data

The knowledge of the potential between interacting colloidal particles is essential to describe and control the aggregation processes in which they are involved. However, interaction forces also bring out spatial ordering phenomena, which has been used to obtain helpful information on them in three-dimensional dispersions. In this paper we look into this possibility for colloidal monolayers spr...

Melting of polydisperse colloidal crystals in nonequilibrium.

The influence of a time-dependent oscillatory external field on the melting transition of a polydisperse colloidal crystal is examined by theory and computer simulation. In a monodisperse crystal the field just induces an overall dynamical mode which does not affect the melting line. For a polydisperse sample, on the other hand, the field shifts the melting line towards smaller temperatures. Co...
