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…

Small field models of inflation that predict a tensor-to-scalar ratio $r = 0.03$

Ira Wolfson, Ram Brustein

Future observations of the cosmic microwave background (CMB) polarization are expected to set an improved upper bound on the tensor-to-scalar ratio of $r ≲ 0.03$ . Recently, w…

Constraints on Scalar and Tensor spectra from $N_{e f f}$

Ido Ben-Dayan, Brian Keating, David Leon +1

At the linear level, the gravitational wave (GW) spectrum predicted by inflation, and many of its alternatives, can have arbitrarily small amplitude and consequently an unconstrain…
