Ground-state phases of a mixture of spin-1 and spin-2 Bose-Einstein condensates
Ground-state phases of a mixture of spin-1 and spin-2 Bose-Einstein condensates
We investigate the ground-state phases of a mixture of spin-1 and spin-2 Bose-Einstein condensates at zero magnetic field. In addition to the intra-spin interactions, two spin-dependent interaction coefficients are introduced to describe the inter-spin interaction. We systematically explore the wide parameter space, and obtain phase diagrams containing a rich variety …
