The effect of shear in self-assembled fluids: The large-N limit

Abstract

The dynamics of self-assembled fluids subjected to a uniform shear are solved for large-N component model of microemulsions. The dynamical structure factor S(k, t) is studied for quenches from an uncorrelated high temperature state into the Lifshitz line within the microemulsion phase. The structure factor shows multiscaling behavior with characteristic length scales (t7/ ln t)1/6 in the flow direction and (t/ ln t)1/6 in directions perpendicular to the flow. The structure factor shows two parallel ridges in the shear-flow plane.
