Due to their long-range and anisotropic interaction, dipoles form an exciting platform to realize quantum phases inaccessible in neutral systems. For Bose-condensed gases in a trap, one such phase is the supersolid where the system forms a crystalline structure while still having a frictionless flow. Even though a trap is needed to realize supersolidity, the theory of the homogeneous gas is important in order to understand experimental results. In this study, we suggest an improved description of the homogeneous dipolar Bose gas where quantum fluctuations are included via the many-body T-matrix. We argue that this description is more rigorous than previous beyond-mean-field approaches. Qualitatively different from bare Bogoliubov theory, we predict the system to be stable for stronger attractive dipole interactions, and argue that quantum fluctuations play an important role in the stabilization of the system.
