Phase-Space Analysis of Quadratic Dark Energy: Stable Attractors and Their Observational Signatures
Sahar Mohammadi, Ebrahim Yusofi, Kosar Asadi
We present a comprehensive phase-space analysis of a quadratic dark energy model where the pressure includes a nonlinear term proportional to the square of the energy density. This…
Stochastic Multiple Fields Inflation: Diffusion Dominated Regime
Kosar Asadi, Amin Nassiri-Rad, Hassan Firouzjahi
We study multiple fields inflation in diffusion dominated regime using stochastic formalism. The fields are under pure Brownian motion in a dS background with boundaries in hi…
Inflation with Stochastic Boundary
Amin Nassiri-Rad, Kosar Asadi, Hassan Firouzjahi
We study the Brownian motion of a field where there are boundaries in the inflationary field space. Both the field and the boundary undergo Brownian motions with the amplitudes of…
Observational constraints on the interacting dark energy - dark matter (IDM) cosmological models
T. Harko, K. Asadi, H. Moshafi +1
Particle creation (or annihilation) mechanisms, described by either quantum field theoretical models, or by the thermodynamics of irreversible processes, play an important role in…
Consistency Relation and Non-Gaussianity in a Galileon Inflation
Kosar Asadi, Kourosh Nozari
We study a particular Galileon inflation in the light of Planck2015 observational data in order to constraint the model parameter space. We study the spectrum of the primordial mod…
The Size of Local Bispectrum and Trispectrum in a Non-Minimal Inflation
Kosar Asadi, Kourosh Nozari
Focusing on the local type primordial non-Gaussianities, we study the bispectrum and trispectrum during a non-minimal slow-roll inflation. We use the so-called formalism to in…
