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…
