Causal Dynamical Triangulations: Gateway to Nonperturbative Quantum Gravity
J. Ambjørn, R. Loll
A powerful strategy to treat quantum field theories beyond perturbation theory is by putting them on a lattice. However, the dynamical and symmetry structure of general relativity…
Lattice Quantum Gravity: EDT and CDT
Jan Ambjorn
This article is an overview of the use of so-called Euclidean Dynamical Triangulations (EDT) and Causal Dynamical Triangulations (CDT) as lattice regularizations of quantum gravity…
The large scale structure of the Universe from a modified Friedmann equation
Jan Ambjorn, Yoshiyuki Watabiki
We have already shown how a modified Friedmann equation, originating from a model of the Universe built from a certain algebra, is able to explainthe difference between the H…
Elementary Quantum Geometry
Jan Ambjorn
These Lecture Notes provide an elementary introduction to the quantization of two-dimensional quantum gravity. Nothing beyond undergratuate physics and mathematic is required. Expl…
Topology induced first-order phase transitions in lattice quantum gravity
J. Ambjorn, J. Gizbert-Studnicki, A. Görlich +1
Causal Dynamical Triangulations (CDT) is a lattice formulation of quantum gravity, suitable for Monte-Carlo simulations which have been used to study the phase diagram of the model…
Easing the Hubble constant tension?
J. Ambjorn, Y. Watabiki
We show how a modified Friedmann equation, originating from a model of the universe built from a certain algebra, has the potential to explain the difference between the Hubb…
