Quintessential Inflation for Exponential Type Potentials: Scaling and Tracker Behavior
Llibert Areste Salo, Jaume Haro
We will show that for exponential type potentials, which are used to depict quintessential inflation, the solutions whose initial conditions take place during the slow roll phase i…
Note on the reheating temperature in Starobinsky-type potentials
Jaume Haro, Llibert Aresté Saló
The relation between the reheating temperature, the number of e-folds and the spectral index is shown for the Starobinsky model and some of its descendants through a very detailed…
Cosmological perturbations in a class of fully covariant modified theories: Application to models with the same background as standard LQC
Jaume de Haro, Llibert Aresté Saló, Emili Elizalde
Bouncing cosmologies are obtained by adding to the Einstein-Hilbert action a term of the form , with a scalar depending on the Hubble parameter only, not on its…
Limiting curvature mimetic gravity and its relation to Loop Quantum Cosmology
Jaume de Haro, Llibert Aresté Saló, Supriya Pan
Considering as usual that the underlying geometry of our universe is well described by the spatially flat Friedmann-Lemaitre-Robertson-Walker line element, we review how the backgr…
