我们从理论上证明了在旋量-187Rb气体中光学控制磁畴的形成是可能的。提出了一个包含光缔合(PA)相互作用的模型,该模型描述了Mf=±1铁磁凝聚体的对称性破缺。我们发现,微区形成的动力学过程可以很大程度上受PA场的控制。PA场可以增强或抑制磁区的空间分离,为调控磁区结构提供了一种灵活的手段,是激光催化旋量凝聚的一个有趣的研究领域。
We show theoretically that it is possible to optically control domain formation in a spinor-1 87Rb gas. A model is proposed to include the photoassociation (PA) interaction characterizing the symmetry breaking of MF = ±1 ferromagnetic condensate. We find that the dynamical process of the domain formation can be greatly controlled by the PA field. The PA field can enhance or suppress the spatial separation of domains, which can provide a flexible tool to modulate the domain structure and indicate an interesting research field of laser-catalyzed in spinor condensate.
