Geometry of the quantum universe
arXiv:1001.4581 · doi:10.1016/j.physletb.2010.05.062
Abstract
A universe much like the (Euclidean) de Sitter space-time appears as background geometry in the causal dynamical triangulation (CDT) regularization of quantum gravity. We study the geometry of such universes which appear in the path integral as a function of the bare coupling constants of the theory.
