An Interacting Two-Fluid Scenario for Dark Energy in FRW Universe
Hassan Amirhashchi, Anirudh Pradhan, Bijan Saha
We study the evolution of the dark energy parameter within the scope of a spatially flat and isotropic Friedmann-Robertson-Walker (FRW) model filled with barotropic fluid and dark…
Bianchi type-II cosmological model: some remarks
Bijan Saha
Within the framework of Bianchi type-II (BII) cosmological model the behavior of matter distribution has been considered. It is shown that the non-zero off-diagonal component of Ei…
Bianchi Type-I Anisotropic Dark Energy Models with Constant Deceleration Parameter
Anirudh Pradhan, H. Amirhashchi, Bijan Saha
New dark energy models in anisotropic Bianchi type-I (B-I) space-time with variable EoS parameter and constant deceleration parameter have been investigated in the present paper. T…
Electromagnetic field with induced massive term: Case with spinor field
Yu. P. Rybakov, G. N. Shikin, Yu. A. Popov +1
We consider an interacting system of spinor and electromagnetic field, explicitly depending on the electromagnetic potentials, i.e., interaction with broken gauge invariance. The L…
Scalar field in cosmology: Potential for isotropization and inflation
Yu. P. Rybakov, G. N. Shikin, Yu. A. Popov +1
The important role of scalar field in cosmology was noticed by a number of authors. Due to the fact that the scalar field possesses zero spin, it was basically considered in isotro…
Bianchi type-VI model with cosmic strings in the presence of a magnetic field
Bijan Saha, Mihai Visinescu
A Bianchi type-VI cosmological model in the presence of a magnetic flux together with a cloud of cosmic strings is considered. In general, the presence of a magnetic field imposes…
