The glass transition in quiescent colloidal suspensions is reasonably well accounted for by a mode coupling theory which treats the collective freezing of density fluctuations but neglects activated processes. In recent years we have extended this approach, with the aid of an exact nonequilibrium Green-Kubo formula, to address the nonlinear rheology of colloidal suspensions. The theory addresses the case of interacting Brownian particles with velocities biased by that of the local fluid flow (assumed homogeneous) thereby ignoring hydrodynamic interactions.

I will discuss the mathematical and numerical problems involved
in coupling atomistic and continuum models as well as coupling
electronic and atomistic models,
with examples from materials and fluids.
