The isotropic attractor solution of axion-SU(2) inflation: Universal isotropization in Bianchi type-I geometry
Ira Wolfson, Azadeh Maleknejad, Tomoaki Murata +2
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 prese…

How attractive is the isotropic attractor solution of axion-SU(2) inflation?
Ira Wolfson, Azadeh Maleknejad, Eiichiro Komatsu
The key to the phenomenological success of inflation models with axion and SU(2) gauge fields is the isotropic background of the SU(2) field. Previous studies showed that this isot…
