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…
Creation of Non-minimal Coupled Particle in Asymptotic de-Sitter Background
E. Yusofi, M. Mohsenzadeh
A general form of quasi-de Sitter(dS) modes in a dynamical background is used to study the creation of particle during the inflation. Actually, by considering the general form of i…
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…
Power Spectrum with Auxiliary Fields in de Sitter Space
M. Mohsenzadeh, M. R. Tanhayi, E. Yusofi
We use the auxiliary fields and (excited-) de Sitter solutions to study the standard power spectrum of primordial fluctuations of a scalar field in the early universe. The auxiliar…
