Chameleon gravity on cosmological scales
H. Farajollahi, A. Salehi
In conventional approach to the chameleon mechanism, by assuming a static and spherically symmetric solutions in which matter density and chameleon field are given by and…
Stability analysis of agegraphic dark energy in Brans-Dicke cosmology
H. Farajollahi, J. Sadeghi, M. Pourali +1
Stability analysis of agegraphic dark energy in Brans-Dicke theory is presented in this paper. We constrain the model parameters with the observational data and thus the results be…
The generalized second law in chameleon cosmology
H. Farajollahi, A. Salehi, F. Tayebi
In this paper, we investigate the validity of the generalized second law (GSL) of thermodynamics in flat FRW chameleon cosmology where the boundary of the universe is assumed to be…
Entropy and statefinder diagnosis in chameleon cosmology
H. Farajollahi, A. Salehi, F. Tayebi
In this paper, the generalized second law (GSL) of thermodynamics and entropy is revisited in the context of cosmological models with bouncing behavior such as chameleon cosmology…
Stability Analysis in Tachyonic Potential Chameleon cosmology
H. Farajollahi, A. Salehi, F. Tayebi +1
We study general properties of attractors for tachyonic potential chameleon scalar-field model which possess cosmological scaling solutions. An analytic formulation is given to obt…
Chameleonic Generalized Brans--Dicke model and late-time acceleration
H. Farajollahi, M. Farhoudi, A. Salehi +1
In this paper we consider Chameleonic Generalized Brans--Dicke Cosmology in the framework of FRW universes. The bouncing solution and phantom crossing is investigated for the model…
