Abstract

Experiments and theories have shown that nematic fluids may adopt inhomogeneous steady states under shear flow. Here we reproduce and study such states by nonequilibrium molec- ular dynamics simulations of systems of soft repulsive ellipsoids. Different situations where a nematic phase coexists with a paranematic phase are examined. In geometries that impose constant stress on the whole system, we observe shear banding, i.e., separation into two phases with different local strain rates.
