Ground states of spin-3 Bose-Einstein condensates for conserved magnetization

Abstract
We calculate the ground states and ground state phase diagrams of Bose-Einstein condensates of spin-3 atoms under the assumption of conserved magnetization. We especially concentrate on the ground states of a chromium condensate. In chromium the magnetic dipole-dipole interaction enables magnetization changing collisions, but in a strong magnetic field these are suppressed. In the calculation of the phase diagrams we neglect the contribution from the dipole-dipole interaction, but discuss its effects at the end of the paper. We show that the ground state of a chromium condensate does not seem to depend on whether or not the dipole-dipole interaction is taken into attention.
