Domain wall formation in the Cahn-Hilliard-Cook equation.
Formation of domain walls during phase-separating transition in the Cahn-Hilliard-Cook equation is studied. Density of domain wall scales like a sixth root of quench rate for equal concentrations and like a square root of quench rate for unequal concentrations of components. For a slow inhomogeneous transition, the density is linear in a velocity of temperature front.
