Machine learning in phase transition analysis of lattice quantum gravity
Jan Ambjorn, Zbigniew Drogosz, Jakub Gizbert-Studnicki +3
Using numerical data coming from Monte Carlo simulations of four-dimensional Causal Dynamical Triangulations, we study how automated machine learning algorithms can be used to reco…
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…
Simulating CDT quantum gravity
Joren Brunekreef, Andrzej Görlich, Renate Loll
We provide a hands-on introduction to Monte Carlo simulations in nonperturbative lattice quantum gravity, formulated in terms of Causal Dynamical Triangulations (CDT). We describe…
Generalised spectral dimensions in non-perturbative quantum gravity
Marcus Reitz, Dániel Németh, Damodar Rajbhandari +2
The seemingly universal phenomenon of scale-dependent effective dimensions in non-perturbative theories of quantum gravity has been shown to be a potential source of quantum gravit…
Scalar fields in Causal Dynamical Triangulations
Jan Ambjørn, Zbigniew Drogosz, Jakub Gizbert-Studnicki +3
A typical geometry extracted from the path integral of a quantum theory of gravity might be quite complicated in the UV region. Even if such a configuration is not physical, it may…
CDT Quantum Toroidal Spacetimes: An Overview
J. Ambjorn, Z. Drogosz, J. Gizbert-Studnicki +3
Lattice formulations of gravity can be used to study non-perturbative aspects of quantum gravity. Causal Dynamical Triangulations (CDT) is a lattice model of gravity that has been…
