We investigated an imbalanced mixture of two-color fermions and scalar bosons in the hard-core limit, considering repulsive and attractive interspecies and intraspecies interactions. The interplay between commensurability, repulsive interactions, and imbalance generates three insulating phases: a mixed Mott state and two spin-selective insulators characterized by specific commensurability relations. State-of-the-art cold-atom setups provide ideal platforms to implement these insulating states and verify their commensurability relations.
We investigate an imbalanced mixture composed of two-color fermions and scalar bosons in the hard-core limit, considering repulsive and attractive interspecies and intraspecies interactions. The interplay between commensurability, repulsive interactions, and imbalance generates three insulating phases: a mixed Mott state and two spin-selective insulators characterized by the commensurability relations rho(B) + rho(up arrow,(down arrow))(F) = 1. For an attractive coupling between fermions and bosons, we found the relations rho(B) - rho(up arrow,(down arrow))(F) = 0 for the spin-selective insulators. State-of-the-art cold-atom setups constitute ideal platforms to implement these unveiled insulating states and verify their commensurability relations.
