Abstract
We investigate the dynamics of a nonequilibrium interface between coex isting phases in a system described by a Cahn-Hilliard equation with a n additional driving term. By means of a matched asymptotic expansion, we derive equations for the interface motion. A linear stability anal ysis of these equations results in a condition for the stability of a flat interface. We find that the stability properties of a flat interf ace depend on the structure of the driving term in the original equati on.
