The predictions of standard Higgs inflation in the framework of the metric formalism yield a
tensor-to-scalar ratio r∼ 10-3 which lies well within the expected accuracy of near-future …

We introduce inflationary models where the inflaton features a field dependent non-minimal
derivative coupling to the Einstein tensor, that we name GNMDC. This Horndeski term gives …

This work is devoted to the construction of slowly rotating neutron stars in the framework of
the nonminimal derivative coupling sector of Horndeski theory. We match the large radius …

This paper is concerned with the construction and analysis of boson stars in the context of
nonminimal derivative coupling theories. In particular, we embed our model in the biscalar …

We propose an inflationary scenario based on the concurrent presence of nonminimal
coupling (NMC) and generalized nonminimal derivative coupling (GNMDC), in the context of …

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 investigate the inflationary predictions of a simple Horndeski theory where the inflaton
scalar field has a non-minimal derivative coupling (NMDC) to the Einstein tensor. The …

We consider, in Palatini formalism, a modified gravity of which the scalar field derivative
couples to Einstein tensor. In this scenario, Ricci scalar, Ricci tensor and Einstein tensor are …

Inspired by thermodynamical dissipative phenomena, we consider bulk viscosity for dark
fluid in a spatially flat two-component Universe. Our viscous dark energy model represents …

Within the framework of metric-affine theories of gravity, where both the metric and
connection are treated as independent variables, we consider actions quadratic in the Ricci …
