Schematic Models for Active Nonlinear Microrheology
Manuel V. Gnann, Igor Gazuz, Antonio M. Puertas +2
We analyze the nonlinear active microrheology of dense colloidal suspensions using a schematic model of mode-coupling theory. The model describes the strongly nonlinear behavior of…
Comment on "Probing the equilibrium dynamics of colloidal hard spheres above the mode-coupling glass transition"
Johannes Reinhardt, Fabian Weysser, Matthias Fuchs
In the Letter [PRL 102, 085703 (2009)] Brambilla, et al. claimed to observe activated dynamics in colloidal hard spheres above the critical packing fraction of mode coupling theory…
Density profiles of a colloidal liquid at a wall under shear flow
J. M. Brader, M. Krüger
Using a dynamical density functional theory we analyze the density profile of a colloidal liquid near a wall under shear flow. Due to the symmetries of the system considered, the n…
Nonlinear response of dense colloidal suspensions under oscillatory shear: Mode-coupling theory and FT-rheology experiments
J. M. Brader, M. Siebenbuerger, M. Ballauff +5
Using a combination of theory, experiment and simulation we investigate the nonlinear response of dense colloidal suspensions to large amplitude oscillatory shear flow. The time-de…
Multiple Glasses in Asymmetric Binary Hard Spheres
Th. Voigtmann
Multiple distinct glass states occur in binary hard-sphere mixtures with constituents of very disparate sizes according to the mode-coupling theory of the glass transition (MCT), d…
Nonlinear rheology of colloidal dispersions
J. M. Brader
Colloidal dispersions are commonly encountered in everyday life and represent an important class of complex fluid. Of particular significance for many commercial products and indus…
