Unification of polynomial and exponential cosmological attractors

Abstract

We introduce a family of simple $\hat{I}\pm$-attractor models that can interpolate between exponential and polynomial cosmological attractors. By varying the interpolation parameter $\hat{I}¼$ in these models, one can scan a wide range of values of the spectral index $n_s$ matching any combination of CMB and DESI data.
