Can breakdown of perturbation in the $α$ -attractor inflation lead to PBH formation?

Chitrak Sarkar, Arunoday Sarkar, Basundhara Ghosh +1

With the basic $α$ -attractor potentials, we investigate an inflationary regime in the high- $k$ limit, where the cosmological perturbation breaks down due to large enhancement in th…

A novel way of constraining the $α$ -attractor chaotic inflation through Planck data

Arunoday Sarkar, Chitrak Sarkar, Buddhadeb Ghosh

Defining a scale of $k$ -modes of the quantum fluctuations during inflation through the dynamical horizon crossing condition $k = a H$ we go from the physical $t$ variable to $k$ var…
