Quantum-cosmological corrections to inflationary spectra from Gaussian wave packets
Sebastien Sonet, Alessandro Tronconi, Giovanni Venturi
In the context of quantum cosmology, we study quantum entanglement in solutions of the Wheeler--DeWitt equation for a homogeneous inflaton--gravity system coupled to perturbations.…

An Effective Theory for Higgs Inflation
A. Tronconi, G. Venturi
The generation of large curvature perturbations associated with the production of primordial black holes is studied in the context of a Higgs inflaton. To enable this amplification…

Scale Invariant Dark Energy
Alessandro Tronconi, Giovanni Venturi
A global scale-invariant Dark Energy model based on Induced Gravity with the addition of a small contribution is examined. The scalar field (quintessence), playing the role o…
