The higher-order phase transition in toroidal CDT
Jan Ambjørn, Grzegorz Czelusta, Jakub Gizbert-Studnicki +3
We investigate the transition between the phases and observed in four-dimensional Causal Dynamical Triangulations (CDT). We find that the critical properties of CDT with…
Towards an UV fixed point in CDT gravity
Jan Ambjørn, Jakub Gizbert-Studnicki, Andrzej Görlich +2
CDT is an attempt to formulate a non-perturbative lattice theory of quantum gravity. We describe the phase diagram and analyse the phase transition between phase B and phase C (whi…
The phase structure of Causal Dynamical Triangulations with toroidal spatial topology
Jan Ambjørn, Jakub Gizbert-Studnicki, Andrzej Görlich +2
We investigate the impact of topology on the phase structure of four-dimensional Causal Dynamical Triangulations (CDT). Using numerical Monte Carlo simulations we study CDT with to…
Four-dimensional CDT with toroidal topology
Jan Ambjørn, Jakub Gizbert-Studnicki, Andrzej Görlich +2
3+1 dimensional Causal Dynamical Triangulations (CDT) describe a quantum theory of fluctuating geometries without the introduction of a background geometry. If the topology of spac…
Four-dimensional Causal Dynamical Triangulations and an effective transfer matrix
Andrzej Görlich
Causal Dynamical Triangulations is a background independent approach to quantum gravity. We show that there exists an effective transfer matrix labeled by the scale factor which pr…
The transfer matrix in four-dimensional Causal Dynamical Triangulations
Andrzej Görlich
Causal Dynamical Triangulations is a background independent approach to quantum gravity. In this paper we introduce a phenomenological transfer matrix model, where at each time ste…
