Length scale dependent relaxation in colloidal gels
E. Del Gado, W. Kob
We use molecular dynamics computer simulations to investigate the relaxation dynamics of a simple model for a colloidal gel at a low volume fraction. We find that due to the presen…
Time Resolved Correlation measurements of temporally heterogeneous dynamics
Agnes Duri, Hugo Bissig, Veronique Trappe +1
Time Resolved Correlation (TRC) is a recently introduced light scattering technique that allows to detect and quantify dynamic heterogeneities. The technique is based on the analys…
Numerical simulation of 2D steady granular flows in rotating drum: On surface flows rheology
Mathieu Renouf, Daniel Bonamy, Frederic Dubois +1
The rheology of 2D steady surface flow of cohesionless cylinders in a rotating drum is investigated through {\em Non Smooth Contact Dynamics} simulations. Profile of volume fractio…
Self-Diffusion and Collective Diffusion of Charged colloids Studied by Dynamic Light Scattering
Jacqueline Appell, Grégoire Porte, Eric Buhler
A microemulsion of decane droplets stabilized by a non-ionic surfactant film is progressively charged by substitution of a non-ionic surfactant molecule by a cationic surfactant. W…
Evidence for the weak steric hindrance scenario in the supercooled-state reorientational dynamics
S. -H. Chong, A. J. Moreno, F. Sciortino +1
We use molecular-dynamics computer simulations to study the translational and reorientational dynamics of a glass-forming liquid of dumbbells. For sufficiently elongated molecules…
Slow dynamics in glassy soft matter
Luca Cipelletti, Laurence Ramos
Measuring, characterizing and modelling the slow dynamics of glassy soft matter is a great challenge, with an impact that ranges from industrial applications to fundamental issues…
