An analytic formula to calculate the reheating temperature via gravitational particle production
Jaume de Haro, Llibert Aresté Saló
We present for smooth non-oscillating backgrounds an analytic formula which calculates the energy density of massive and massless particles created via gravitational particle produ…
Well-posedness of the four-derivative scalar-tensor theory of gravity in singularity avoiding coordinates
Llibert Aresté Saló, Katy Clough, Pau Figueras
We show that the most general scalar-tensor theory of gravity up to four derivatives in dimensions is well-posed in a modified version of the CCZ4 formulation of the Einstein…
The problem of calculating the -Bogoliubov coefficient in Non-Oscillating models
Jaume de Haro, Llibert Aresté Saló
The calculation of the Bogoliubov coefficients is a key piece to obtain the reheating temperature of the Universe. In all cases this calculation is performed either in toy models w…
Gravitational particle production of superheavy massive particles in Quintessential Inflation II: -attractors
Llibert Aresté Saló, Jaume de Haro
We compute the gravitational production of conformally coupled superheavy particles during the phase transition from the end of inflation to the beginning of kination for -attra…
A review of Quintessential Inflation
Jaume de Haro, Llibert Aresté Saló
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…
The spectrum of Gravitational Waves, their overproduction in quintessential inflation and its influence in the reheating temperature
Jaume Haro, Llibert Aresté Saló
One of the most important issues in an inflationary theory as standard or quintessential inflation is the mechanism to reheat the universe after the end of the inflationary period…
