The isotropic attractor solution of axion-SU(2) inflation: universal isotropization in Bianchi type-I geometry
SU(2) gauge fields coupled to an axion field can acquire an isotropic background solution during inflation. We study homogeneous but anisotropic inflationary solutions in the presence of such (massless) gauge fields. A gauge field in the cosmological background may pose a threat to spatial isotropy....
