Abstract
We investigate the newly discovered supersolid phase by solving in random phase approximation the anisotropic Heisenberg model of the hard-core boson He lattice. We include nearest and next-nearest neighbor interactions and calculate exactly all pair correlation functions in a cumulant expansion scheme. We describe the properties of the normal solid and supersolid phases and argue that based on analogies to the fermionic half filled extended Hubbard model the supersolid state corresponds to a bond-ordered-wave.
