Decay of dark energy into dark matter in a metric gravity: effective running Hubble constant
Giovanni Montani, Mariaveronica De Angelis, Maria Giovanna Dainotti
We examine a modified late-Universe dynamics where dark energy decays into dark matter, within the framework of metric -gravity in the Jordan frame. After a detailed analysis…
Inflation in non-local hybrid metric-Palatini gravity
Flavio Bombacigno, Mariaveronica De Angelis, Carsten van de Bruck +1
Within the framework of hybrid metric-Palatini gravity, we incorporate non-localities introduced via the inverse of the d'Alembert operators acting on the scalar curvature. We anal…
WKB Approaches to Restore Time in Quantum Cosmology: Predictions and Shortcomings
Giulia Maniccia, Mariaveronica De Angelis, Giovanni Montani
In this review, we analyse different aspects concerning the possibility to separate a gravity-matter system into a part which lives close to a quasi-classical state and a "small" q…
Quantum Dynamics of the Isotropic Universe in the Metric f(R) Gravity
Mariaveronica De Angelis, Laria Figurato, Giovanni Montani
We analyse the canonical quantum dynamics of the isotropic universe, as emerging from the Hamiltonian formulation of a metric f(R) gravity, viewed in the Jordan frame. The canonica…
Dynamics of quantum anisotropies in a Taub Universe in the WKB approximation
Mariaveronica De Angelis, Giovanni Montani
We analyze the dynamics of a Taub cosmological model in the presence of a massless minimally coupled scalar field and a cosmological constant, in the limit when both the Universe v…
