Interacting Holographic Extended Chaplygin Gas and Phantom Cosmology in the Light of BICEP2
J. Sadeghi, H. Farahani, B. Pourhassan
In this paper, we study the holographic dark energy density and interacting extended Chaplygin gas energy density in the Einstein gravity. We reconstruct the scalar field and the s…
Extended Chaplygin Gas in Horava-Lifshitz Gravity
B. Pourhassan
In this paper, we investigate cosmological models of the extended Chaplygin gas in a universe governed by Horava-Lifshitz gravity. The equation of state for an extended Chaplygin g…
Tachyonic matter cosmology with exponential and hyperbolic potentials
B. Pourhassan, J. Naji
In this paper we consider tachyonic matter in spatially at FRW universe, and obtain behavior of some important cosmological parameters for two special cases of potentials. First we…
An effective quintessence field with a power-law potential
M. Khurshudyan, B. Pourhassan, R. Myrzakulov +1
In this paper, we consider an effective quintessence scalar field with a power-law potential interacting with a barotropic fluid as a first model, where is a de…
Higher derivative corrections of gravity with varying equation of state in the case of variable and
M. Khurshudyan, B. Pourhassan, A. Pasqua
In this paper, we study three models of f(R) modified gravity including higher order terms based on different equation of state parameter. We also assume variable G and . By usi…
