Abstract

Renormalization group approach for low-dimensional dilute Bose gases is generalized for 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.

PACS: 67.85.Fg Multicomponent condensates; spinor condensates;
PACS: 67.60.Bc Boson mixtures;
PACS: 37.10.Jk Atoms in optical lattices.

Key words: ultracold atoms, spinor bosons, low dimension.
