IR and UV limits of CDT and their relations to FRG
Jan Ambjorn, Jakub Gizbert-Studnicki, Andrzej Goerlich +1
Causal Dynamical Triangulations (CDT) is a lattice theory of quantum gravity. It is shown how to identify the IR and the UV limits of this lattice theory with similar limits studie…
Is Lattice Quantum Gravity Asymptotically Safe? Making contact between Causal Dynamical Triangulations and the Functional Renormalization Group
Jan Ambjørn, Jakub Gizbert-Studnicki, Andrzej Gőrlich +1
We compare the effective action of the scale factor obtained from lattice quantum gravity (in the form of Causal Dynamical Triangulations (CDT)) to the corresponding effective acti…
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…
