Stability of low-dimensional multicomponent Bose gases
arXiv:0903.1647 · doi:10.1103/PhysRevA.81.013601
Abstract
I show that in low dimensions the interactions in dilute Bose mixtures are strongly renormalized, which leads to a considerable change of stability conditions compared to the mean-field results valid in the high-density regime. Estimates are given for the two-component Bose-Hubbard model and for the Rb(87)-K(41) mixture.
