Abstract

We demonstrate the formation of two types of symbiotic nondipolar droplet supersolid in a binary dipolar-nondipolar mixture with an interspecies atraction, where the dipolar (nondipolar) atoms are trapped (untrapped). In the absence of an interspecies attraction, in the first type, a dipolar droplet supersolid exists, whereas in the second type, there are no droplets in the dipolar component. To illustrate, we consider a $^{164}$ Dy- $^{87}$ Rb mixture, where the untrapped $^{87}$ Rb supersolid sticks to the trapped $^{164}$ Dy supersolid due to the interspecies attraction and forms a symbiotic supersolid with overlapping droplets. The first (second) type of symbiotic supersolid emerges for the scattering length $a_{1} = 85 a_{0}$ ( $a_{1} = 95 a_{0}$ ) of $^{164}$ Dy atom, while under an appropriate trap a dipolar droplet supersolid exists (does not exist) for no interspecies interaction, where $a_{0}$ the Bohr radius. This study is based on the numerical solution of an improved binary mean-field model, where we introduce an intraspecies Lee-Huang-Yang interaction in the dipolar component, which stops a dipolar collapse and forms a dipolar supersolid.To observe this symbiotic droplet supersolid, one should prepare the corresponding fully trapped dipolar-nondipolar supersolid and then remove the trap on the nondipolar atoms.
