Interactions in low-dimensional spinor bosonic gases

The renormalization group approach for low-dimensional dilute Bose gases is generalized to the case of multicomponent bosons. As an example, systems of two- and three-component spinor bosons are considered. It is shown that interatomic interactions are strongly renormalized with a tendency to enhance the interaction symmetry. (c) 2010 American Institute of Physics. [doi:10.1063/1.3499234]
