Anomalous Relaxation in Entropic Colloidal Gels

Abstract
Brownian motion in depletion-force networks is studied with video microscopy in confined nearly hard-sphere mixtures. The particle trajectories show anomalous diffusion, while the self part of the van Hove correlation function exhibits a novel scaling in terms of its first moment. A simple model is used to extract the weak elastic modulus of the gel.Citation
