Abstract EN
This article addresses the issue of possible gravitational phase transitions in the early universe.
We suggest that a second-order phase transition observed in the Causal Dynamical Triangulations approach to quantum gravity may have a cosmological relevance.
The phase transition interpolates between a nongeometric crumpled phase of gravity and an extended phase with classical properties.
Transition of this kind has been postulated earlier in the context of geometrogenesis in the Quantum Graphity approach to quantum gravity.
We show that critical behavior may also be associated with a signature change in Loop Quantum Cosmology, which occurs as a result of quantum deformation of the hypersurface deformation algebra.
In the considered cases, classical space-time originates at the critical point associated with a second-order phase transition.
Relation between the gravitational phase transitions and the corresponding change of symmetry is underlined.
