How round is the quantum de Sitter universe?
N. Klitgaard, R. Loll
We investigate the quantum Ricci curvature, which was introduced in earlier work, in full, four-dimensional quantum gravity, formulated nonperturbatively in terms of Causal Dynamic…
Quantizing quantum Ricci curvature
N. Klitgaard, R. Loll
Quantum Ricci curvature has been introduced recently as a new, geometric observable characterizing the curvature properties of metric spaces, without the need for a smooth structur…
Introducing Quantum Ricci Curvature
N. Klitgaard, R. Loll
Motivated by the search for geometric observables in nonperturbative quantum gravity, we define a notion of coarse-grained Ricci curvature. It is based on a particular way of extra…
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…
