Constraints of anisotropy on warm power-law inflation in light of Planck results
Zahra Ghadiri, Ali Aghamohammadi, Abdollah Refaei
In this article, we examine the effects of anisotropy on a model of canonical warm inflation with the power-law potential. The results of this model are compared to Planck satellit…
Non-canonical scalar field in low anisotropy universe with intermediate inflation
Mahdeyeh Naderi, Ali Aghamohammadi, Abdollah Refaei +1
The behaviour of a non-canonical scalar field within an anisotropic Bianchi type I, spatially homogeneous, Universe in the framework of the intermediate inflation will be studied.…
Constraints on warm power-law inflation in light of Planck results
Zahra Ghadiri, Abdollah Refaei, Ali Aghamohammadi +1
The constraints on a general form of the power-law potential and the dissipation coefficient in the framework of warm single field inflation imposed by Planck data will be investig…
Effects of low anisotropy on interacting holographic and new agegraphic scalar fields models of dark energy
Hossien Hossienkhani, Ali Aghamohammadi, S. W. Rabieei +1
A spatially homogeneous and anisotropic Bianchi type I universe is studied with the interacting holographic and new agegraphic scalar fields models of dark energy. Given, the frame…
Dissipative noninteracting scalar field theory: A covariant formulation
A. Refaei, F. Kheirandish
Caldeira-Leggett model of reservoir is generalized to a reservoir modeled by a continuum of real Klein-Gordon fields, instead of harmonic oscillators. A quantum Langevin type dissi…

In this paper, the λϕ^4 scalar feld effective action, in the one-loop approximation, is calculated by using the Krein space quantization. We show that the effective action is natur…
QED effective action in Krein space quantization
A. Refaei, M. V. Takook
The one-loop effective action of QED is calculated by the Schwinger method in Krein space quantization. We show that the effective action is naturally fnite and regularized. It als…
