Preheating after Multifield Inflation with Nonminimal Couplings, I: Covariant Formalism and Attractor Behavior
Matthew P. DeCross, David I. Kaiser, Anirudh Prabhu +2
This is the first of a three-part series of papers, in which we study the preheating phase for multifield models of inflation involving nonminimal couplings. In this paper, we stud…
Fermion production during and after axion inflation
Peter Adshead, Evangelos I. Sfakianakis
We study derivatively coupled fermions in axion-driven inflation, specifically and monodromy inflation, and calculate particle production during the inflationary epoch a…
Leptogenesis from left-handed neutrino production during axion inflation
Peter Adshead, Evangelos I. Sfakianakis
We propose that the observed matter-antimatter asymmetry can be naturally produced as a byproduct of axion-driven slow-roll inflation by coupling the axion to standard-model neutri…
Gauge-preheating and the end of axion inflation
Peter Adshead, John T. Giblin, Timothy R. Scully +1
We study the onset of the reheating epoch at the end of axion-driven inflation where the axion is coupled to an Abelian, , gauge field via a Chern-Simons interaction term. We…
