Torsion of Space-time in f(R) gravity
Majid Mohsenzadeh, Ebrahim Yusofi
In this paper, we first review some aspects of the f(R) gravity and then the concept of torsion of space-time due to metric-affine formalism in f(R) gravity is studied. Within this…
Friedmann-like equations for High Energy Area of Universe
E. Yusofi, M. Mohsenzadeh
In this paper, evolution of the high energy area of universe, through the scenario of 5 dimensional (5D) universe, has been studied. For this purpose, we solve Einstein equations f…
Trans-Planckian Scale and Krein Space Quantization
A. Sojasi, M. Mohsenzadeh
In this work, Krein space quantization method is applied to eliminate the Ultraviolet divergence of Green functions. This paper shows that the power spectrum of scalar field fluctu…
Spectrum of Gravitational Waves in Krein Space Quantization
M. Mohsenzadeh, A. Sojasi, E. Yusofi
The main goal of this paper is to derive the primordial power spectrum for the scalar perturbations generated as a result of quantum fluctuations during an inflationary pe- riod by…
Evolution of Bulk Scale Factor in Warped Space-time
M. Mohsenzadeh, E. Yusofi
In this work the role of extra dimensions in the accelerated universe through the scenario of higher-dimensional Friedmann-Robertson-Walker (FRW) cosmology has been studied. For th…
