Ground-state structure and stability of dipolar condensates in anisotropic traps

We study the Hartree ground state of a dipolar condensate of atoms or molecules in a three-dimensional anisotropic geometry and at T=0. We determine the stability of the condensate as a function of the aspect ratios of the trap frequencies and of the dipolar strength. We find numerically a rich phase space structure characterized by various structures of the ground-state density profile.
