Stability of a Nonequilibrium Interface in a Driven Phase Segregating System
arXiv:patt-sol/9705010 · doi:10.1103/PhysRevE.57.47
Abstract
We investigate the dynamics of a nonequilibrium interface between coexisting phases in a system described by a Cahn-Hilliard equation with an additional driving term. By means of a matched asymptotic expansion we derive equations for the interface motion. A linear stability analysis of these equations results in a condition for the stability of a flat interface. We find that the stability properties of a flat interface depend on the structure of the driving term in the original equation.
