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…
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…
Collective excitations in quantum gravity condensates
Andrea Calcinari, Adrià Delhom, Daniele Oriti
A central open problem in quantum gravity is to understand how continuum spacetime emerges from quantum-geometric degrees of freedom in a background-independent setting. A many-bod…
