GFiRe: a Gauge Field integrator for Reheating
Kaloian D. Lozanov, Mustafa A. Amin
We present a new numerical algorithm and code, , for solving the non-linear evolution of Abelian gauge fields coupled to complex scalar fields in homogeneous and isotr…
Lectures on Reheating after Inflation
Kaloian D. Lozanov
This lecture note provides a generic introduction to reheating after inflation, covering theoretical, phenomenological and observational aspects of the process.
Production and Backreaction of Fermions from Axion- Gauge Fields during Inflation
Leila Mirzagholi, Azadeh Maleknejad, Kaloian D. Lozanov
gauge fields and axions can have a stable, isotropic and homogeneous configuration during inflation. However, couplings to other matter species lead to particle production,…
Gravitational perturbations from oscillons and transients after inflation
Kaloian D. Lozanov, Mustafa A. Amin
We study the scalar and tensor perturbations generated by the fragmentation of the inflaton condensate into oscillons or transients after inflation, using nonlinear classical latti…
