We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

We study the general features of a dynamics of a phantom field in the cosmological context.
In the case of an inverse coshyperbolic potential, we demonstrate that the phantom field can …

In this paper, we propose a novel mechanism in Bbb T 2-inflation to enhance the power
spectrum large enough to seed primordial black holes (PBHs) formation. To accomplish this, we …

We study the evolution of (phantom) dark energy universe by taking into account the higher-order
string corrections to Einstein–Hilbert action with fixed dilaton and modulus fields. While …

We investigate inflationary dynamics in the framework of the Einstein-Gauss-Bonnet gravity.
In the model under consideration, the inflaton field is nonminimally coupled to the Gauss-…

We consider the framework of quintessential inflation in the warm background which is
caused by the dissipation of the scalar field energy density into relativistic degrees of freedom. …

Quintessential inflation refers to scenarios in which a single scalar field is used to describe
inflation and late time acceleration. This review is dedicated to the framework of …

Presently, climate change is considered as a serious global environmental challenge
influencing growth and survival of pathogens of many food- and water-borne diseases as well as …

We investigate the scalar field dynamics of models with nonminimally coupled scalar fields
in the presence of the Gauss-Bonnet term and derive the structure of the effective potential …

In this paper, we examine chaotic inflation within the context of the energy–momentum
squared gravity (EMSG) focusing on the energy–momentum powered gravity (EMPG) that …
