Active and Nonlinear Microrheology in Dense Colloidal Suspensions (2008)
Gazuz, I., Puertas, A. M., Voigtmann, Th., Fuchs, M.
We present a first-principles theory for the active nonlinear microrheology of colloidal model systems: for constant external force on a spherical probe particle embedded in a dense host dispersion,...
Henrich, O., Puertas, A. M., Sperl, M., Baschnagel, J., Fuchs, M.
A colloidal system of spheres interacting with both a deep and narrow attractive potential and a shallow long-ranged barrier exhibits a prepeak in the static structure factor. This peak can be...
Competition between glass transition and liquid-gas separation in attracting colloids (2006)
Puertas, A. M., Fuchs, M., Cates, M. E.
We present simulation results addressing the phenomena of colloidal gelation induced by attractive interactions. The liquid-gas transition is prevented by the glass arrest at high enough attraction...
Tagged-particle dynamics in a hard-sphere system: mode-coupling theory analysis (2004)
Voigtmann, Th., Puertas, A. M., Fuchs, M.
The predictions of the mode-coupling theory of the glass transition (MCT) for the tagged-particle density-correlation functions and the mean-squared displacement curves are compared quantitatively...
Theory and simulation of gelation, arrest and yielding in attracting colloids (2004)
Cates, M. E., Fuchs, M., Kroy, K., Poon, W. C. K., Puertas, A. M.
We present some recent theory and simulation results addressing the phenomena of colloidal gelation at both high and low volume fractions, in the presence of short-range attractive interactions. We...
