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…
