Characteristics of the new phase in CDT

J. Ambjørn, J. Gizbert-Studnicki, A. Görlich +3

Causal Dynamical Triangulations (CDT), a candidate theory of nonperturbative quantum gravity in 4D, turns out to have a rich phase structure. We investigate the recently discovered…

Impact of topology in causal dynamical triangulations quantum gravity

Jan Ambjorn, Zbigniew Drogosz, Jakub Gizbert-Studnicki +3

We investigate the impact of spatial topology in 3+1 dimensional causal dynamical triangulations (CDT) by performing numerical simulations with toroidal spatial topology instead of…

Renormalization Group Flow in CDT

J. Ambjorn, A. Goerlich, J. Jurkiewicz +2

We perform a first investigation of the coupling constant flow of the nonperturbative lattice model of four-dimensional quantum gravity given in terms of Causal Dynamical Triangula…

Quantum Spacetime, from a Practitioner's Point of View

J. Ambjorn, S. Jordan, J. Jurkiewicz +1

We argue that theories of quantum gravity constructed with the help of (Causal) Dynamical Triangulations have given us the most informative, quantitative models to date of quantum…

CDT meets Horava-Lifshitz gravity

J. Ambjorn, A. Gorlich, S. Jordan +2

The theory of causal dynamical triangulations (CDT) attempts to define a nonperturbative theory of quantum gravity as a sum over space-time geometries. One of the ingredients of th…

Geometry of the quantum universe

J. Ambjorn, A. Goerlich, J. Jurkiewicz +1

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…
