Renormalization in quantum theories of geometry
J. Ambjorn, J. Gizbert-Studnicki, A. Goerlich +2
A hallmark of non-perturbative theories of quantum gravity is the absence of a fixed background geometry, and therefore the absence in a Planckian regime of any notion of length or…
Critical Phenomena in Causal Dynamical Triangulations
J. Ambjorn, D. Coumbe, J. Gizbert-Studnicki +2
Four-dimensional CDT (causal dynamical triangulations) is a lattice theory of geometries which one might use in an attempt to define quantum gravity non-perturbatively, following t…
The Semiclassical Limit of Causal Dynamical Triangulations
J. Ambjorn, A. Gorlich, J. Jurkiewicz +3
Previous work has shown that the macroscopic structure of the theory of quantum gravity defined by causal dynamical triangulations (CDT) is compatible with that of a de Sitter univ…
