Dynamics of the self-interacting chameleon cosmology
Hossein Farajollahi, Amin Salehi
In this article we study the properties of the flat FRW chameleon cosmology in which the cosmic expansion of the Universe is affected by the chameleon field and dark energy. In par…
Constraints on scalar-tensor theories from observations
Hossein Farajollahi, Amin Salehi, Mohammad Nasiri
We study the dynamical description of scalar-tensor gravity by performing the best-fit analysis for two cases of exponential and power-law form of the potential and scalar field fu…
Dynamical stability in scalar-tensor cosmology
H. Farajollahi, A. Shahabi, A. Salehi
We study FRW cosmology for a double scalar - tensor theory of gravity where two scalar fields are nonminimally coupled to the geometry. In a framework to study stability and attrac…
Stability analysis and observational constraints in scalar tensor theory
Hossein Farajollahi, Amin Salehi, Mohammad Nasiri
We study FRW cosmology for scalar tensor theory where two scalar functions nonminimally coupled to the geometry and matter Lagrangian. In a framework to study stability and attract…
Geometric and thermodynamic properties in Gauss-Bonnet gravity
Hossein Farajollahi, Amin Salehi
In this paper, the generalized second law (GSL) of thermodynamics and entropy is revisited in the context of cosmological models in Gauss-Bonnet gravity with the boundary of the un…
Observational constraints in scalar tensor theory with tachyonic potential
H. Farajollahi, A. Salehi, A. Shahabi
We study the dynamics of the scalar tensor cosmological model in the presence of tachyon field. In an alternative approach, in two exponential and power law form of the scalar fiel…
