Abstract: The competition between tunneling and interactions in bosonic lattice modelsgenerates a whole variety of different quantum phases. While, in the presenceof a single species interacting via on-site interaction, the phase diagrampresents only superfluid or Mott insulating phases, for long-range interactionsor multiple species, exotic phases such as supersolid SS or pair-superfluidPSF appear. In this work, we show for the first time that the co-existence ofeffective multiple species and long-range interactions leads to the formationof a novel pair-supersolid PSS phase, namely a supersolid of composites. Wepropose a possible implementation with dipolar bosons in a bilayertwo-dimensional optical lattice.
