Quantum Gravity via Causal Dynamical Triangulations
J. Ambjorn, A. Goerlich, J. Jurkiewicz, R. Loll
http://arxiv.org/abs/1302.2173v1 (8 Feb 2013)

"Causal Dynamical Triangulations" (CDT) represent a lattice regularization of the sum over spacetime histories, providing us with a non-perturbative formulation of quantum gravity. The ultraviolet fixed points of the lattice theory can be used to define a continuum quantum field theory, potentially making contact with quantum gravity defined via asymptotic safety. We describe the formalism of CDT, its phase diagram, and the quantum geometries emerging from it. We also argue that the formalism should be able to describe a more general class of quantum-gravitational models of Horava-Lifshitz type.
