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…
Semiclassical and Continuum Limits of Four-Dimensional CDT
Jakub Gizbert-Studnicki
This article discusses the infrared and the (perspective) ultraviolet limits of four-dimensional Causal Dynamical Triangulations (CDT). CDT is a non-perturabtive and background-ind…
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…
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…
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…
