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…
