论文摘要
我们研究了由两色费米子和标量玻色子组成的不平衡混合物，并考虑了折叠和有吸引力的种间和种内相互作用。可辨式，排斥性相互作用和不平衡之间的相互作用产生了三个绝缘阶段：混合Mott状态和两个以可辨别性关系为特征的自旋选择性绝缘子$ρ_b+ρ^{\ UPAROW，（\ downarrow）} _ f = 1 $。对于Fermions和Bosons之间的有吸引力的耦合，我们找到了关系$ρ_b-ρ^{\ UPARROW，（\ downarrow）} _ f = 0 $用于自旋选择性绝缘子。最先进的冷原子设置构成了实施这些揭露的绝缘状态并验证其可怜性关系的理想平台。
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 $ρ_B+ρ^{\uparrow,(\downarrow)}_F=1$. For an attractive coupling between fermions and bosons, we found the relations $ρ_B-ρ^{\uparrow,(\downarrow)}_F=0$ for the spin-selective insulators. State-of-the-art cold-atoms setups constitute ideal platforms to implement these unveiled insulating states and verify their commensurability relations.
