Cosmic Acceleration from Quantum Gravity: Emergent Inflation and Dynamical Dark Energy
Luca Marchetti, Tom R. Ladstätter, Daniele Oriti
We present a mechanism for the emergence of cosmic acceleration within the mean-field approximation of Group Field Theory models of quantum gravity. Depending on the interaction ty…
Interacting Scalar Field Cosmology from Full Quantum Gravity
Tom R. Ladstätter, Luca Marchetti
We study the relational cosmological dynamics emerging from interacting group field theory (GFT) models minimally coupled to a massless clock scalar field and a self-interacting sc…
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…
