Phase Separation and Coarsening in Electrostatically Driven Granular Media
Phase Separation and Coarsening in Electrostatically Driven Granular Media
A continuum model for the phase separation and coarsening in electrostatically driven granular media is formulated in terms of a Ginzburg-Landau equation subject to conservation of the total number of grains. In the regime of well-developed clusters, the continuum model is used to derive ``sharp-interface'' equations that govern the dynamics …
