Abstract

We study the effect of interactions between dipole moments of grains exposed to strong electric field gradients, and we find that several novel behaviors appear, including dynamical dust swirls and a variety of vertical columns and filaments of grains. We find that we can qualitatively reproduce most observed experimental phenomena in simple simulations, and we demonstrate that the observed phenomena are a direct consequence of intrinsic nonlinear electrostatic interactions between neighboring particles. We close by drawing a parallel between granular electrostatics and the better-established field of celestial mechanics, since both fields involve multi-body forces governed by an inverse-squared law.
