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…
Emergence of Spacetime from Fluctuations
Marcus Reitz, Barbara Šoda, Achim Kempf
We use a result of Hawking and Gilkey to define a Euclidean path integral of gravity and matter which has the special property of being independent of the choice of basis in the sp…
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…
Approximate Killing symmetries in non-perturbative quantum gravity
Joren Brunekreef, Marcus Reitz
It is an open question whether fluctuations at the Planck scale in a non-perturbative theory of quantum gravity behave in such a way that the resulting semi-classical geometry can…
Geometric flux formula for the gravitational Wilson loop
N. Klitgaard, R. Loll, Marcus Reitz +1
Finding diffeomorphism-invariant observables to characterize the properties of gravity and spacetime at the Planck scale is essential for making progress in quantum gravity. The ho…
The higher-order spectrum of simplicial complexes: a renormalization group approach
Marcus Reitz, Ginestra Bianconi
Network topology is a flourishing interdisciplinary subject that is relevant for different disciplines including quantum gravity and brain research. The discrete topological object…
