Cosmic acceleration and phantom crossing in -gravity
H. Farajollahi, A. Ravanpak, P. Wu
In this paper, we propose two new models in gravity to realize universe acceleration and phantom crossing due to dark torsion in the formalism. The model parameters are cons…
Curvaton reheating and intermediate inflation in brane cosmology
H. Farajollahi, A. Ravanpak
In this paper, we study the curvaton reheating mechanism for an intermediate inflationary universe in brane world cosmology. In contrast to our previous work, we assume that when t…
Cosmography in f(T)-gravity
S. Capozziello, V. F. Cardone, H. Farajollahi +1
Being based on the only assumption that the universe is homogenous and isotropic on large scales, cosmography is an ideal tool to investigate the cosmic expansion history in a almo…
Dynamics of the universe as a "test 3-brane" in a 5D bulk
Hossein Farajollahi, Arvin Ravanpak
In this paper we study the dynamics of a 5D bulk space-time with our universe as a "test 3-brane" located in the bulk, an idealized model of a topological object whose physical pro…
Interacting Holographic dark energy in chameleon tachyon cosmology
H. Farajollahi, A. Ravanpak, G. Farpour Fadakar
We propose in this paper an interacting holographic dark energy (IHDE) model in chameleon--tachyon cosmology by interaction between the components of the dark sectors. In the forma…
Tachyon Field in Intermediate Inflation on the Brane
H. Farajollahi, A. Ravanpak
We propose a new model of inflation in the framework of brane cosmology in the presence of tachyonic field. we derive the expressions for the model parameters in brane inflation, a…
