Stripe-on-plane-wave phase of a binary dipolar Bose gases with soft-core long-range interactions

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.

Automated summary

The study maps out the ground-state phase diagrams of a binary Bose-Einstein condensate with long-range dipolar and soft-core interactions, considering the orientation of the dipoles. The results demonstrate a variety of ground state phases, such as supersolid, standing wave, and stripe-on-plane wave phases, resulting from the interplay between long-range isotropic and anisotropic interactions.
