Primordial black holes and slow-roll violation
H Motohashi, W Hu - Physical Review D, 2017 - APS
For primordial black holes (PBH) to be the dark matter in single-field inflation, the slow-roll
approximation must be violated by at least O (1) in order to enhance the curvature power …

Non-Gaussianity from step features in the inflationary potential
We provide analytic solutions for the power spectrum and bispectrum of curvature
fluctuations produced by a step feature in the inflaton potential, valid in the limit that the step …
