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…
Like-charge attraction in confinement: myth or truth ?
Joerg Baumgartl, Jose Luis Arauz-Lara, Clemens Bechinger
It is general wisdom that likely charged colloidal particles repel each other when suspended in liquids. This is in perfect agreement with mean field theories being developed more…
New Light on Like-Charge Attraction
Joerg Baumgartl, Jose Luis Arauz-Lara, Clemens Bechinger
We report on pair interaction measurements in charged colloidal systems in confined and unconfined geometries by means of optical microscopy. At very small particle distances we ob…
