Two-component bosonic mixtures on the three-dimensional cubic lattice
Abstract
Abstract We investigate the extended Bose–Hubbard model of two bosonic components, on a cubic lattice. Utilizing the dynamical Gutzwiller mean-field theory, we discover the counterflow supersolid state, characterized by the modulated checkerboard order, critically coexisting with a characteristic of the counterflow superfluid. The standard supersolid state of checkerboard order is further identified. And it could be governed by the phase-separation, via an adjustment of the inter-component interaction. Finally, we also chart out the relevant phase diagram.
