含偶极作用 BEC 的相分离

two-component BEC, in which the atoms in component 1 have a magnetic dipolemoment and the atoms in component 2 are nonmagnetic, are considered. The problem is studied by means of numerical simulations. The effects of dipole-dipole interaction on phase separations are investigated. It is shown that, in the quasi-one-dimensional regime, the atoms in component 2 are squeezed out when the dimensionless dipolar strength parameter is small, whereas the atoms in component 1 are pushed out instead when the parameter is large. Another phenomena that these two components are both kicked out by each other in the quasi-one-dimensional regime is discussed as well.
