In this paper, we review in detail different mechanisms of generation of large primordial
fluctuations and their implications for the production of primordial black holes (PBHs) and …

Abstract Using the Effective Field Theory (EFT) framework of single field inflation, we
investigate the possibility of the formation of Primordial Black Holes (PBHs) in the Slow Roll …

Using the δN formalism we calculate the one-loop correction to the large-scale power
spectrum of the curvature perturbation in the standard scenario where primordial black holes …

We present a detailed exposition on the prospects of the formation of Primordial Black Holes
(PBHs) during Slow Roll (SR) to Ultra Slow Roll (USR) sharp transitions in the framework of …

We examine the possibility of Primordial Black Holes (PBHs) formation in single field models
of inflation. Using the adiabatic or wave function renormalization scheme in the short range …

We consider Galileon inflation in the Effective Field Theory (EFT) framework and examine
the possibility for PBH formation during slow roll (SR) to ultra slow roll (USR) transitions. We …

The most promising mechanism of generating PBHs is by the enhancement of power
spectrum of the primordial curvature perturbation, which is usually accompanied by the the …

Single-field models of inflation might lead to amplified scalar fluctuations on small scales
due, for example, to a transient ultra-slow-roll phase. It was argued by Kristiano & Yokoyama …

Single field models of inflation capable of producing primordial black holes usually require a
significant departure from the standard, perturbative slow-roll regime. In fact, in many of …

We investigate the explicit role of negative local non-Gaussianity, f NL, in suppressing the
abundance of primordial black holes (PBHs) in the single-field model of Galileon inflation …
