Reconstruction of initial Asymptotic-de Sitter mode in light of the Planck data
Hossein Moshafi, Ata Sojasi, Ebrahim Yusofi +1
The recently relased \emph{Planck} data, emphasize that the background geometry of inflation is not pure de Sitter, but from the slow variation of Hubble parameter during the infla…
Large Angular Scale CMB Anisotropy from an Excited Initial Mode
A. Sojasi, M. Mohsenzadeh, E. Yusofi
According to inflationary cosmology, the CMB anisotropy gives an opportunity to test predictions of new physics hypotheses. The initial state of quantum fluctuations is one of the…
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…
