| Zusammenfassung: | 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. |
