CDT and cosmology

Publication date: Available online 26 May 2017 Source:Comptes Rendus Physique Author(s): Lisa Glaser, Renate Loll In the approach of Causal Dynamical Triangulations (CDT), quantum gravity is obtained as a scaling limit of a non-perturbative path integral over space-times whose causal structure plays a crucial role in the construction. After some general considerations about the relation between quantum gravity and cosmology, we examine which aspects of CDT are potentially interesting from a cosmological point of view, focusing on the emergence of a de Sitter universe in CDT quantum gravity.
