Gauge-flation and Cosmic No-Hair Conjecture

TL;DR

This paper investigates gauge-flation, a model of inflation driven by non-Abelian gauge fields, and demonstrates through analysis that isotropic inflation is a stable attractor, supporting the cosmic no-hair conjecture by showing anisotropies decay rapidly.

Contribution

The study provides analytic and numeric evidence that gauge-flation naturally leads to isotropic inflation, confirming the cosmic no-hair conjecture within this framework.

Findings

Isotropic FLRW inflation is an attractor in gauge-flation.

Anisotropies decay within a few e-folds.

Supports the cosmic no-hair conjecture in gauge-flation.

Abstract

Gauge-flation, inflation from non-Abelian gauge fields, was introduced in [1,2]. In this work, we study the cosmic no-hair conjecture in gauge-flation. Starting from Bianchi-type I cosmology and through analytic and numeric studies we demonstrate that the isotropic FLRW inflation is an attractor of the dynamics of the theory and that the anisotropies are damped within a few e-folds, in accord with the cosmic no-hair conjecture.
