Inflationary quasiscale-invariant attractors
Inflationary quasiscale-invariant attractors
In a series of recent papers Kallosh, Linde, and collaborators provide a unified description of single-field inflation with several types of potentials ranging from power law to supergravity, in terms of just one parameter $\ensuremath{\alpha}$. These so-called $\ensuremath{\alpha}$ attractors predict a spectral index ${n}_{s}$ and a tensor-to-scalar ratio $r$, which …
