Supersolid in Bose-Bose-Fermi Mixtures subjected to a Square Lattice

Abstract

Two-component Bose condensates with repulsive interaction are stable when $g_1{g}_2<g_{12}^2$ is satisfied. By tuning the interactions, we show that the instability corresponding to bose-bose phase separation always happens at a higher temperature than corresponding to bose-fermi phase separation happens. Moreover, we find both the transition temperature $T_{\mathrm{DW}}$ of supersolid and the coherence peak at $k_{\mathrm{DW}}$ are enhanced in the mixtures studied. These will make the observation of supersolid in experiments more reachable.
