Non-Markovian open quantum system approach to the early universe: I. Damping of gravitational waves by matter
Moslem Zarei, Nicola Bartolo, Daniele Bertacca +2
By revising the application of the open quantum system approach to the early universe and extending it to the conditions beyond the Markovian approximation, we obtain a new non-Mar…
Two-Field quintessential Higgs Inflation
Mehdi Eshaghi, Moslem Zarei, Ahmad Sheykhi
We study a two-field quintessential Higgs inflation model in which a quintessence field with an exponential potential is coupled to the Higgs field from the beginning…
CMB and reheating constraints to α-attractor inflationary models
Mehdi Eshaghi, Moslem Zarei, Nematollah Riazi +1
After Planck 2013, a broad class of inflationary models called α-attractors was developed which has universal observational predictions. For small values of the parameter α, the mo…
Generation of CMB B-mode Polarization from Circular Polarization
Rohoollah Mohammadi, Moslem Zarei
In this work we consider non-zero circular polarization for the CMB radiation as a result of new interactions. We then rewrite the Boltzmann equations for the Stokes parameters …
Anisotropic Inflation from Charged Scalar Fields
Razieh Emami, Hassan Firouzjahi, S. M. Sadegh Movahed +1
We consider models of inflation with U(1) gauge fields and charged scalar fields including symmetry breaking potential, chaotic inflation and hybrid inflation. We show that there e…
