Phase Separation and Coarsening in Electrostatically Driven Granular Media
arXiv:cond-mat/0107443 · doi:10.1103/PhysRevLett.88.204301
Abstract
A continuum model for the phase separation and coarsening, observed 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 of the interphase boundary. The model captures the essential physics of this system.
