Phonon dispersion curves of two-dimensional colloidal crystals: on the wavelength dependence of friction
Joerg Baumgartl, Julian Dietrich, Jure Dobnikar +2
Digital video-microscopy measurements are reported of both elastic bandstructures and overdamped phonon decay times in two-dimensional colloidal crystals. Both quantities together…
Three-body interactions in colloidal systems
J. Dobnikar, M. Brunner, H. H. von Grünberg +1
We present the first direct measurement of three-body interactions in a colloidal system comprised of three charged colloidal particles. Two of the particles have been confined by…
Direct measurement of three-body interactions
M. Brunner, J. Dobnikar, H. H. von Grünberg +1
Three-body interactions have been measured among three charged colloidal particles in deionized solvent. Two of the particles have been confined to an optical line-trap while the t…
Characterizing Potentials by a Generalized Boltzmann Factor
V. Blickle, T. Speck, U. Seifert +1
Based on the concept of a nonequilibrium steady state, we present a novel method to experimentally determine energy landscapes acting on colloidal systems. By measuring the station…
The Einstein relation generalized to non-equilibrium
V. Blickle, T. Speck, C. Lutz +2
The Einstein relation connecting the diffusion constant and the mobility is violated beyond the linear response regime. For a colloidal particle driven along a periodic potential i…
Experimental observation of structural crossover in binary mixtures of colloidal hard spheres
Jörg Baumgartl, Roel P. A. Dullens, Marjolein Dijkstra +2
Using confocal-microscopy we investigate the structure of binary mixtures of colloidal hard spheres with size ratio q=0.61. As a function of the packing fraction of the two particl…
