Unification of polynomial and exponential cosmological attractors
Abstract
We introduce a family of simple α-attractor models that can interpolate between exponential and polynomial cosmological attractors. By varying the interpolation parameter μ in these models, one can scan a wide range of values of the spectral index ns matching any combination of CMB and DESI data.
