Jamming, hysteresis and oscillation in scalar models for shear thickening
D. A. Head, A. Ajdari, M. E. Cates
We investigate shear thickening and jamming within the framework of a family of spatially homogeneous, scalar rheological models. These are based on the `soft glassy rheology' mode…

Crossover to Self-Organized Criticality in an Inertial Sandpile Model
D. A. Head, G. J. Rodgers
We introduce a one-dimensional sandpile model which incorporates particle inertia. The inertial dynamics are governed by a new parameter which, as it passes through a threshold val…
