摘要
We numerically investigate the ground-state properties of a trapped Bose-Einstein condensate with quadrupole-quadrupole interaction. We quantitatively characterize the deformations of the condensate induced by the quadrupolar interaction. We also map out the stability diagram of the condensates and explore the trap geometry dependence of the stability.
