The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Some of the most important quintessential inflation scenarios, such as the Peebles–Vilenkin
model, are described in detail. These models are able to explain the early-and late-time …

We investigate the production process of induced gravity waves due to large scalar
fluctuations in the paradigm of quintessential inflation. We numerically solve the Mukhanov …

Primordial black holes (PBHs) can generically form in inflationary setups through the
collapse of enhanced cosmological perturbations, providing us access to the early Universe …

In this work, we present a quintessential interpretation of having a blue-tilted tensor power
spectrum for canonical single-field slow-roll inflation to explain the recently observed …

We study the cosmological inflation within the context of f (Q, T) gravity, wherein Q is the
nonmetricity scalar and T is the trace of the matter energy–momentum tensor. By choosing a …

A novel approach to quintessential inflation model building is studied, within the framework
of α-attractors, motivated by supergravity theories. Inflationary observables are in excellent …

We construct a model of quintessential inflation in Palatini R 2 gravity employing a scalar
field with a simple exponential potential and coupled to gravity with a running non-minimal …

We study quintessential inflation using a generalized exponential potential V (ϕ)∝ exp (− λ
ϕ n/M Pl n), n> 1, the model admits slow-roll inflation at early times and leads to close-to …

The article presents modeling of inflationary scenarios for the first time in the f (R, T) theory of
gravity. We assume the f (R, T) functional form to be R+ η T R+ η T, where R denotes the …
