Ratcheting of driven attracting colloidal particles: temporal density oscillations and current multiplicity.
We consider the unidirectional particle transport in a suspension of colloidal particles which interact with each other via a pair potential having a hard-core repulsion plus an attractive tail. The colloids are confined within a long narrow channel and are driven along by a dc or an ac external potential. In addition, the walls of the channel interact with the particles via a ratchetlike perio...
متن کاملEvaporation-driven assembly of colloidal particles.
Colloidal particles absorbed at the interface of a liquid droplet arrange into unique packings during slow evaporation [V.N. Manoharan et al., Science 301, 483 (2003)]. We present a numerical and theoretical analysis of the packing selection problem. The selection of a unique packing arises almost entirely from geometrical constraints during the drying.
متن کاملHydrodynamic pair attractions between driven colloidal particles.
Colloidal spheres driven through water along a circular path by an optical ring trap display unexpected dynamical correlations. We use Stokesian dynamics simulations and a simple analytical model to demonstrate that the path's curvature breaks the symmetry of the two-body hydrodynamic interaction, resulting in particle pairing. The influence of this effective nonequilibrium attraction diminishe...

15 صفحه اولDressing of driven colloidal particles in a subcritical liquid suspension.
At equilibrium, colloidal particles in a subcritical liquid suspension are surrounded by a drying layer if the colloid has solvophobic interaction. Using Brownian dynamics computer simulations, we investigate the nonequilibrium response of this layer to a strong external driving force. We find that the driven colloidal particle dresses itself with more particles than in the equilibrium drying l...
