Accelerating Universe in Terms of Hankel Function Index
K. Suratgar, M. Mohsenzadeh, E. Yusofi +1
In this paper, cosmology is proposed for the accelerating universe with asymptotic de Sitter expansion in terms of Hankel function index . To some extent, both the initia…
A possible role for the merger of clusters/voids in the cosmological expansion
S. Mohammadi, E. Yusofi, M. Mohsenzadeh +1
In this study, we use the merger process of clusters/voids in the role of variable dark energy fluid to alleviate the Hubble tension, which can lead to a balance in the cosmologica…
Quasi-de Sitter Solution, Negative Norm State and Krein Space in Cosmology
Majid Mohsenzadeh
Recent observational data have shown two important results about cosmic inflation: First, the primordial power spectrum is approximately scale invariant. Secondly, the space-time g…
Non-Linear Trans-Planckian Corrections of Spectra due to the Non-trivial Initial States
E. Yusofi, M. Mohsenzadeh
Recent Planck results motivated us to use non-Bunch-Davies vacuum. In this paper, we use the excited-de Sitter mode as non-linear initial states during inflation to calculate the c…
Bulk Scale Factor at Very Early Universe
M. Mohsenzadeh, E. Yusofi
In this paper we propose a higher dimensional Cosmology based on FRW model and brane-world scenario. We consider the warp factor in the brane-world scenario as a scale factor in 5-…
