Asymmetric Reheating of Dark QED
Simon Cléry, Jean Kimus, Michel H. G. Tytgat
We study in detail a scenario in which the inflaton scalar field couples to both a visible sector (VS) and a hidden sector (HS). The VS is assumed to contain the Standard Model (SM…

Generalizing the Bogoliubov vs Boltzmann approaches in gravitational production
Ayan Chakraborty, Simon Clery, Md Riajul Haque +2
We investigate the spectral behavior of scalar fluctuations generated by gravity during inflation and the subsequent reheating phase. We consider a non-perturbative Bogoliubov trea…

Bare mass effects on the reheating process after inflation
Simon Clery, Marcos A. G. Garcia, Yann Mambrini +1
We consider the effects of a bare mass term for the inflaton, when the inflationary potential takes the form about its minimum with . We concentrate on $k=…
