Emergent time, cosmological constant and boundary dimension at infinity in combinatorial quantum gravity

Abstract Combinatorial quantum gravity is governed by a discrete Einstein-Hilbert action formulated on an ensemble of random graphs. There is strong evidence for a second-order quantum phase transition separating a random phase at strong coupling from an ordered, geometric phase at weak coupling. He...
