Lattice Simulations of Abelian Gauge Fields coupled to Axion during Inflation

  title={Lattice Simulations of Abelian Gauge Fields coupled to Axion during Inflation},
  author={Angelo Caravano and Eiichiro Komatsu and Kaloian D. Lozanov and Jochen Weller},
We use 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. This kind of models have already been studied with a lattice simulation in the context of reheating. In this work, we focus on the deep inflationary phase and discuss the new aspects that need to be considered in order to simulate gauge fields in this regime. Our main result is reproducing with precision the growth of the gauge field on…

The limits of the perturbative treatment that connects inflationary potential parameters to primordial power spectrum observables are probes and it is shown that the validity of analytic approximations of the scalar index roughly respects the large-field/small-field dichotomy.

On Adiabatic Renormalization with a Physically Motivated Infrared Cut-Off
. We introduce a new approach to renormalize physical quantities in curved space-time by adiabatic subtraction. We use a comoving infrared cut-off in defining the adiabatic counterpart of the physical


On the validity of the perturbative description of axions during inflation
Axions play a central role in many realizations of large field models of inflation and in recent alternative mechanisms for generating primordial tensor modes in small field models. If these axions
Lattice simulations of inflation
This paper uses a lattice simulation to reproduce the well-known results of some simple models of single-field inflation, particularly for the scalar field perturbation.
Gauge-preheating and the end of axion inflation
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
Non-Abelian Gauge Field Inflation
In [arXiv:1102.1513] we introduced an inflationary scenario, Non-Abelian Gauge Field Inflation or gauge-flation for short, in which slow-roll inflation is driven by non-Abelian gauge field minimally
Lattice formulation of axion inflation. Application to preheating
We present a lattice formulation of an interaction ${\phi\over\Lambda} F\tilde F$ between an axion and some $U(1)$ gauge sector with the following properties: it reproduces the continuum theory up to
Natural inflation on a steep potential with classical non-Abelian gauge fields.
It is found that inflation continues until the axionic potential vanishes, and for sub-Planckian axion decay constants vanishingly small tensor to scalar ratios are predicted, a direct consequence of the Lyth bound.
Reheating the universe after multi-field inflation
We study in detail (p)reheating after multi-field inflation models with a particular focus on N-flation. We consider a variety of different couplings between the inflatons and the matter sector,
Nonlinear perturbations from the coupling of the inflaton to a non-Abelian gauge field, with a focus on Chromo-Natural Inflation
Several models of inflation employing a triplet of SU(2) vectors with spatially orthogonal vacuum expectation values (VEVs) have been recently proposed. One (tensor) combination $t$ of the vector
Magnetogenesis from axion inflation
In this work we compute the production of magnetic fields in models of axion inflation coupled to the hypercharge sector of the Standard Model through a Chern-Simons interaction term. We make the
