An Asymptotic Method for Selection of Inflationary Modes
E. Yusofi, M. Mohsenzadeh
We present some features of early universe cosmology in terms of Hankel functions index (). Actually, the recent data from observational cosmology indicate that our universe was…
Particle Creation and Excited-de Sitter Modes
M. Mohsenzadeh, E. Yusofi
Recently, in Ref.\cite{moh1}, we introduced exited-de Sitter modes to study the power spectrum which was finite in Krein space quantization and the trans-Plankian corrections due t…
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…
Inflation in Non-de Sitter Background with Coherent States
E. Yusofi, M. Mohsenzadeh, M. R. Tanhayi
We use the excited coherent states built over the initial non-de Sitter modes, to study the modification of spectra of primordial scalar fluctuation. Non-de Sitter modes are actual…
Scale-dependent power spectrum from initial excited-de Sitter modes
E. Yusofi, M. Mohsenzadeh
In this paper, we calculate corrections of scalar perturbations spectra resulting from excited-de Sitter modes as the nontrivial initial states. To obtain these modes, we consider…
