Abstract:

A new type of the interface dynamics in the late stage of the phase separation process at the critical quench is derived with use of an intuitive solution for the Dirichlet problem of the diffusion equation with the Gibbs-Thomson boundary condition. A quasistatic approximation is used. In the well-known Green formula a mean shielding length is introduced phenomenologically for the charge induction on the earthed random interface. A smoothing process through the diffusion current along the random interface is incorporated in a unified equation with the usual evaporation-condensation process. Both processes are consistent with the t1/3-evolution law.
