Shear-jammed, fragile, and steady states in homogeneously strained granular materials
We study the jamming phase diagram of sheared granular material using a novel Couette
shear setup with a multiring bottom. The setup uses small basal friction forces to apply a …

Dynamic vorticity banding in discontinuously shear thickening suspensions
It has recently been argued that steady-state vorticity bands cannot arise in shear thickening
suspensions because the normal stress imbalance across the interface between the bands …

Microscopic origin of frictional rheology in dense suspensions: correlations in force space
We develop a statistical framework for the rheology of dense, non-Brownian suspensions,
based on correlations in a space representing forces, which is dual to position space …
