Title: Commensurate mixtures of ultracold atoms in one dimension

Abstract

We study binary mixtures of ultracold atoms, confined to one dimension in an optical lattice, with commensurate densities. Within a Luttinger liquid description, which treats various mixtures on equal footing, we derive a system of renormalization group equations at second order, from which we determine the rich phase diagrams of these mixtures. These phases include charge and spin density wave orders, singlet and triplet pairings, polaron pairing [L. Mathey et al., Phys. Rev. Lett. 93, 120404 (2004)], and a supersolid phase. Various methods to detect our results experimentally are discussed.
