Gravitational particle production of superheavy massive particles in Quintessential Inflation: A numerical analysis
Llibert Aresté Saló, Jaume de Haro
We compute numerically the reheating temperature due to the gravitational production of conformally coupled superheavy particles during the phase transition from the end of inflati…
Theoretical and observational bounds on some interacting vacuum energy scenarios
Weiqiang Yang, Supriya Pan, Llibert Aresté Saló +1
The dynamics of interacting dark matter-dark energy models is characterized through an interaction rate function quantifying the energy flow between these dark sectors. In most of…
attractors in Quintessential Inflation motivated by Supergravity
Llibert Aresté Saló, David Benisty, Eduardo I. Guendelman +1
An exponential kind of quintessential inflation potential motivated by supergravity is studied. This type belongs to the class of α-attractor models. The model was studied for the…
Gravitational production of superheavy baryonic and dark matter in quintessential inflation: nonconformally coupled case
Jaume Haro, Llibert Aresté Saló
The gravitational production of superheavy dark matter is studied in the context of quintessential inflation. The superheavy particles, whose decay products are baryonic matter and…
Understanding gravitational particle production in quintessential inflation
Jaume de Haro, Supriya Pan, Llibert Aresté Saló
The diagonalization method, introduced by a group of Russian scientists at the beginning of seventies, is used to compute the energy density of superheavy massive particles produce…
Reheating constraints in quintessential inflation
Jaume de Haro, Llibert Aresté Saló
We study the consequences of reheating in quintessential inflation. From simple inflationary quintessential models introduced in cite{hap, hap2}, we show that when the reheating is…
Cosmological solutions in spatially curved universes with adiabatic particle production
Llibert Aresté Saló, Jaume de Haro
We perform a qualitative and thermodynamic study of two models when one takes into account adiabatic particle production. In the first one, there is a constant particle production…
