We study models of nonminimally coupled relativistic fluid and the k-essence scalar field in
the background of a flat Friedmann-Lemaitre-Robertson-Walker universe. The nonminimal …

In this paper we investigate a non-minimal, space-time derivative dependent, coupling
between the k-essence field and a relativistic fluid using a variational approach. The …

We reconsider the dynamical systems approach to analyze inflationary universe in the
Jordan frame models of scalar field nonminimally coupled to curvature. The adopted set of …

In this article, we try to determine the conditions when a ghost field, in conjunction with a
barotropic fluid, produces a stable accelerating expansion phase of the universe. It is seen …

We perform the dynamical system analysis of a cosmological model in the energy–
momentum squared gravity (EMSG) of the form f (T μ ν T μ ν)= α ln (λ T μ ν T μ ν), which is …

The theory of gravity with a quadratic contribution of scalar curvature is investigated using a
dynamical systems approach. The simplest Friedmann–Robertson–Walker metric is …

In this work we have studied a cosmological model based on a quintom dark energy model
non-minimally coupled with gravity, endowed with a specific potential energy of the …

Non-minimal coupled scalar field models are well-known for providing interesting
cosmological features. These include a late-time dark energy behavior, a phantom dark …

Editor: P. Brax The theory of gravity with a quadratic contribution of scalar curvature is
investigated using a dynamical systems approach. The simplest Friedmann–Robertson …

In this paper, we model the bounce phase, stability and the reconstruction of the universe by
non-minimal kinetic coupling. In the process, we obtained importance information about the …
