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 …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

This white paper summarizes recent progress in the cosmological bootstrap, an approach to
the study of the statistics of primordial fluctuations from consistency with unitarity, locality and …

We revisit the one-loop correction in curvature perturbation power spectrum in models of
single field inflation which undergo a phase of ultra slow-roll (USR) inflation. We include the …

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 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 …

In canonical single-field inflation, the production of primordial black holes (PBH) requires a
transient violation of the slow-roll condition. The transient ultra slow-roll inflation is an …

Nonlocal primordial non-Gaussianity (NLPNG) is a smoking gun of interactions in single-
field inflationary models and can be written as a combination of the equilateral and …

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 …

Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …
