Demixing and symmetry breaking in binary dipolar Bose-Einstein condensate solitons
arXiv:1401.3184 · doi:10.1103/PhysRevA.89.013630
Abstract
We demonstrate fully demixed (separated) robust and stable bright binary dipolar Bose-Einstein condensate soliton in a quasi-one-dimensional setting formed due to dipolar interactions for repulsive contact interactions. For large repulsive interspecies contact interaction the first species may spatially separate from the second species thus forming a demixed configuration, which can be spatially-symmetric or symmetry-broken. In the spatially-symmetric case, one of the the species occupies the central region, whereas the other species separates into two equal parts and stay predominantly out of this central region. In the symmetry-broken case, the two species stay side by side. Stability phase diagrams for the binary solitons are obtained. The results are illustrated with realistic values of parameters in the binary 164Dy-168Er and 164Dy-162Dy mixtures. The demixed solitons are really soliton molecules formed of two types of atoms. A proposal for creating dipolar solitons in experiments is also presented.
