@article{Adshead2015GaugepreheatingAT, title={Gauge-preheating and the end of axion inflation}, author={Peter Adshead and John T. Giblin and Timothy R. Scully and Evangelos I. Sfakianakis}, journal={Journal of Cosmology and Astroparticle Physics}, year={2015}, volume={2015}, pages={034-034} }

We study the onset of the reheating epoch at the end of axion-driven inflation where the axion is coupled to an Abelian, U(1), gauge field via a Chern-Simons interaction term. We focus primarily on m22 inflation and explore the possibility that preheating can occur for a range of coupling values consistent with recent observations and bounds on the overproduction of primordial black holes. We find that for a wide range of parameters preheating is efficient. In certain cases the inflaton…

This work uses a non-linear lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction and identifies a discretization scheme for which the growth of the gauge field on the lattice reproduces the one of continuous space with good precision.

The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically…
