摘要/Abstract

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.

关键词: quadrupole-quadrupole interactions, trapped Bose-Einstein condensates, ground state, stability, deformations, collective excitations
