Abstract
We propose a model with quantum bosons on the fcc lattice, which has a stable algebraic Bose liquid phase at low energy. We show that this phase is described by emergent quantum gravity at the Gaussian Lifshitz fixed point in dimensions. The stability of this algebraic Bose liquid phase is guaranteed by the gauge symmetry of gravitons and self-duality of the low-energy field theory. By tuning one parameter in the lattice boson model we can drive a phase transition between the Lifshitz gravity and another algebraic Bose liquid phase, described by gravity at the Lifshitz point.
