Emergent scalar field dynamics in a cosmological spacetime from GFT quantum gravity
Roukaya Dekhil, Federico Greco, Stefano Liberati +1
We derive an effective scalar field theory for matter in group field theory condensate cosmology, starting from the fundamental quantum-gravity dynamics in a fully relational frame…

Finite path integrals on stochastic branched structures
Roukaya Dekhil, Clifford Ellgen, Bruno Klajn
In this paper, we present a statistical model of spacetime trajectories based on a finite collection of paths organized into a branched manifold. For each configuration of the bran…
