Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
Scalar Cosmological Perturbations from Quantum Gravitational Entanglement
Alexander F. Jercher, Luca Marchetti, Andreas G. A. Pithis
A major challenge at the interface of quantum gravity and cosmology is to explain the emergence of the large-scale structure of the Universe from Planck scale physics. In this lett…
Scale invariance beyond criticality within the mean-field analysis of tensorial field theories
Roukaya Dekhil, Alexander F. Jercher, Daniele Oriti +1
We continue the series of articles on the application of Landau-Ginzburg mean-field theory to unveil the basic phase structure of tensorial field theories which are characterized b…
Phase transitions in TGFT: Landau-Ginzburg analysis of the causally complete Lorentzian Barrett-Crane model
Roukaya Dekhil, Alexander F. Jercher, Andreas G. A. Pithis
It is expected that continuum spacetime emerges via phase transition in the tensorial group field theory (TGFT) approach to quantum gravity. Recent work on the application of Landa…
