Position dependence of Nielsen complexity for the Thermofield double state
F. Khorasani, Reza Pirmoradian, Mohammad Reza Tanhayi
In this paper, the Nielsen geometric method is used to study the position dependence of the Nielsen complexity for the thermofield double state of a harmonic oscillator. We present…
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…
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…
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…
Radiation effects on particle's trajectory in the linear level
M. Fathi, M. Tanhayi-Ahari, M. R. Tanhayi +1
In this work, we first obtain the linear form of the scalar self-force and then, the effect of self-force on the particle's trajectory is considered. In de Sitter space-time, withi…
Casimir Effect For a Scalar Field via Krein Quantization
H. Pejhan, M. Reza Tanhayi, M. V. Takook
In this work, we present a rather simple method to study the Casimir effect on a spherical shell for a massless scalar field with Dirichlet boundary condition by applying the indef…
Auxiliary "massless" spin-2 field in de Sitter universe
H. Pejhan, M. R. Tanhayi, M. V. Takook
For the tensor field of rank-2 there are two unitary irreducible representation (UIR) in de Sitter (dS) space denoted by and [1]. In the flat limit…
Conformal linear gravity in de Sitter space
M. V. Takook, M. R. Tanhayi, S. Fatemi
It has been shown that the theory of linear conformal quantum gravity must include a tensor field of rank-3 and mixed symmetry [1]. In this paper, we obtain the corresponding field…
Linear Weyl Gravity in de Sitter Universe
M. V. Takook, M. R. Tanhayi
In this paper we obtain the linear Weyl gravity in de Sitter background. Its linear form in five-dimensional ambient space notation has also been obtained. From the group theoretic…
