Rheology, Diffusion and Plastic Correlations in Jammed Suspensions

We present results using Durian's bubble model [1] to study the spatio- temporal correlations and rheological response to imposed shear ow in steady state in jammed suspensions of soft, frictionless disks. We firrst study the so- called mean drag (MD) variant of the model which is appropriate for modeling particles at interfaces where the dominant dissipation comes from motion of the particle with respect to the phases o the interface.
