WebIn this paper we consider FRW cosmology in $${F(R,\\phi)}$$ gravity. It is shown that in particular cases the bouncing behavior may appears in the model whereas the equation of state (EoS) parameter may crosses the phantom divider. For the dynamical universe, quantitatively we also find parameters in the model which satisfies two independent … WebMay 2, 2012 · We consider modified theories of gravity with a direct coupling between matter and geometry, denoted by an arbitrary function in terms of the Ricci scalar. Due to such a coupling, the matter stress tensor is no longer conserved and there is an energy transfer between the two components. By solving the conservation equation, we argue … WebModified gravity can be considered as an alternative to dark energy. In a generalized theory of gravity, the Universe may accelerate while containing only baryonic and dark matter. chocista

WebThis is the underlying philosophy of what is referred to as f (R) gravity [19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31]. It has been suggested that these modified gravity models account for the late time acceleration of the universe [24], … WebJan 30, 2024 · Some of the typical viable f(R) gravity models have been discussed to fit the cosmological evolutions [9]. It has been shown that the viable f(R) gravity can perfectly describe the power spectrum of the matter density fluctuation [10,11,12,13,14] and the formation of the large scale structure (LSS) [15,16,17,18].

WebThe gravitational phase shift of neutrino oscillation can be discussed in the framework of f(R)-gravity. We show that the shift of quantum mechanical phase can depend on the given f(R)-theory that we choose. This fact is general and could constitute a fundamental test to discriminate among the various alternative relativistic theories of gravity. WebJan 31, 2024 · There are three versions of f(R) gravity: Metric-f(R) theory (second order formalism) is fully described by the metric field alone, Palatini-f(R) theory (first order formalism) in which metric and connection are handled as independent fields, similarly the“metric-affine f(R) theory”in which matter Lagrangian also includes connection [].In …
