The authors use molecular dynamics (MD) simulation methods to investigate dusty plasma crystal structure in an external potential, with the grains subject to both a spherically symmetric Debye-Hueckel potential and a cylindrically symmetric dipole interaction. The dipole contribution models the experimentally important effects of ion flow or intrinsic grain polarization. They find that the addition of a small dipole term changes the crystal structure from bct to one in which the grains are aligned vertically, consistent with experiments as well as recent theoretical calculations.
