Emergent dark sector in group field theory cosmology
Andrea Calcinari, Federico Greco, Daniele Oriti +1
We develop an analytical treatment of the emergent cosmological dynamics induced by local polynomial interactions in a deparametrised group field theory model, moving beyond the us…
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…
Gauge versus (hidden) physical symmetries of FLRW cosmologies
Andrea Calcinari, Adrià Delhom, Federico Greco +2
In generally covariant theories, evolution in coordinate time is a gauge transformation, so that a symmetry made manifest in a gauge-fixed description need not be a symmetry of the…
