Computersimulation of colloidal particles in two-dimensional channel geometries. — •Ullrich Siems and Peter Nielaba — University of Konstanz, Germany

This talk will present the results of Brownian Dynamics Simulations of colloidal particles in external fields confined in two-dimensional channels. Superparamagnetic Brownian particles are well suited 2d model-systems for a variety of problems on different length scales, ranging from pedestrian walking through a bottleneck to ions passing ion-channels in living cells. In such systems confinement into channels can have a great influence on the diffusion and transport properties. In our study interacting colloidal particles were dragged over a washboard potential and are additionally confined in a two-dimensional micro-channel.
