长程相互作用在自然界中普遍存在，并在各种物理领域中进行研究。超冷量子气体中软核长程相互作用的实现拓宽了长程相互作用的研究领域。我们考虑了具有长程偶极相互作用和长程软核相互作用的二元玻色-爱因斯坦凝聚。系统的基态相图已被绘制出在全参数空间占的偶极和软核的长程相互作用，以及偶极子的取向。结果表明，长程各向同性和各向异性相互作用之间的相互作用的结果在各种基态相，如超固体，驻波，和条纹平面波相。特别是，偶极和软核长程相互作用的影响，连同偶极子的取向，也被讨论在每个基态阶段。这些参数的实验可行性均在目前的实验能力范围内。
Long-range interactions are ubiquitous in nature and are studied in a variety of physical fields. The recent realization of soft-core long-range interaction in ultracold quantum gases broadens the research field of long-range interactions. We consider a binary Bose–Einstein condensate with both long-range dipolar and long-range soft-core interactions. The ground-state phase diagrams of the system have been mapped out in full parameter space accounting for the dipolar and soft-core long-range interactions, as well as the orientation of the dipoles. The results show that the interplay between long-range isotropic and anisotropic interactions results in a variety of ground state phases, such as supersolid, standing wave, and stripe-on-plane-wave phases. In particular, the effects of dipolar and soft-core long-range interaction, together with the orientation of the dipoles, have also been discussed in each ground state phase. The experimental feasibility of the parameters are within the current experimental capacity.
