摘要
The anisotropy of dipole-dipole interaction is revealed by energy band,tunneling dynamics and stabilities of a dipolar condensate in one-dimensional optical lattices.It is demonstrated that the Bloch band structure,the tunneling rate between Bloch bands and the stabilities of Bloch states can be controlled by adjusting the effective aspect ratio of the condensate and the dipolar orientation.
