We explore the prospects for direct detection of dark energy by current and upcoming
terrestrial dark matter direct detection experiments. If dark energy is driven by a new light …

Since the discovery of the accelerated expansion of the present universe, significant
theoretical developments have been made in the area of modified gravity. In the meantime …

In this work we investigate several theoretical and phenomenological implications of a
scalar-F (R) gravity containing a non-minimal coupling to the scalar curvature. This kind of …

We study spherically symmetric configurations of the quadratic f (R) gravity [f (R)= RR 2/6 μ
2]. In the case of a purely gravitational system, we have fully investigated the global …

We show that a large class of modified gravity theories (MOG) with the Jordan-frame
Lagrangian f (R) translate into scalar-field (scalaron) models with hilltop potentials in the …

We reexamine the static and spherical symmetric compact star configuration in the R 2
model of the F (R) gravity theory. With asymptotic solutions for the additional scalar degrees …

We explore the scalar field obtained under the conformal transformation of the spacetime
metric g μν from the Jordan frame to the Einstein frame in f (R) gravity. This scalar field is the …

A new cosmological scenario is proposed in which a light scalaron of f (R) gravity plays the
role of dark matter. In this scenario, the scalaron initially resides at the minimum of its …

The scalaron of the metric f (R) gravity can constitute dark matter if its mass is in the range 4
meV≲ m≲ 1 MeV. We give an overview of such f (R) gravity theory minimally coupled to the …

Toward understanding of dark energy, we propose a novel method to directly produce a
chameleon particle and force its decay under controlled gas pressure in a laboratory-based …
