Cosmological Attractors from $\alpha$-Scale Supergravity
  The Planck value of the spectral index can be interpreted as $n_s = 1 - 2/N$
in terms of the number of e-foldings $N$. An appealing explanation for this
phenomenological observation is provided by $\alpha$-attractors: the
inflationary predictions of these supergravity models are fully determined by
the curvature of the Kahler manifold. We provide a novel formulation of
$\alpha$-attractors which only involves a single chiral superfield. Our
construction involves a natural deformation of no-scale models, and employs
these to construct a De Sitter plateau with an exponential fall-off. Finally,
we show how analogous structures with a flat Kahler geometry arise as a
singular limit of such $\alpha$-scale models.
