Power spectrum of inflationary attractors

Inflationary attractors predict the spectral index and tensor-to-scalar ratio to take specific values that are consistent with Planck. An example is the universal attractor for models with a generalized nonminimal coupling, leading to Starobinsky inflation. In this paper we demonstrate that it also...
