Query: Bose-Einstein condensation of trapped atoms with dipole interactions   The path integral Monte Carlo method is used to simulate dilute trapped Bose
gases and to investigate the equilibrium properties at finite temperatures. The
quantum particles have a long-range dipole-dipole interaction and a short-range
s-wave interaction. Using an anisotropic pseudopotential for the long-range
dipolar interaction and a hard-sphere potential for the short-range s-wave
interaction, we calculate the energetics and structural properties as a
function of temperature and the number of particles. Also, in order to
determine the effects of dipole-dipole forces and the influence of the trapping
field on the dipolar condensate, we use two cylindrically symmetric harmonic
confinements (a cigar-shaped trap and a disk-shaped trap). We find that the net
effect of dipole-dipole interactions is governed by the trapping geometry. For
a cigar-shaped trap, the net contribution of dipolar interactions is attractive
and the shrinking of the density profiles is observed. For a disk-shaped trap,
the net effect of long-range dipolar forces is repulsive and the density
profiles expand.
