Properties of dynamical fractal geometries in the model of Causal Dynamical Triangulations
arXiv:2007.13311 · doi:10.1103/PhysRevD.103.086022
Abstract
We investigate the geometry of a quantum universe with the topology of the four-torus. The study of non-contractible geodesic loops reveals that a typical quantum geometry consists of a small semi-classical toroidal bulk part, dressed with many outgrowths, which contain most of the four-volume and which have almost spherical topologies, but nevertheless are quite fractal.
