Anisotropic Inflation with the non-Vacuum Initial State
Razieh Emami, Hassan Firouzjahi, Moslem Zarei
In this work we study models of anisotropic inflation with the generalized non-vacuum initial states for the inflaton field and the gauge field. The effects of non Bunch-Davies ini…
Primordial Anisotropies in Gauged Hybrid Inflation
Ali Akbar Abolhasani, Razieh Emami, Hassan Firouzjahi
We study primordial anisotropies generated in the model of gauged hybrid inflation in which the complex waterfall field is charged under a gauge field. Primordial anisotropi…
Spectroscopy of Masses and Couplings during Inflation
Razieh Emami
In this work, we extend the idea of Quasi Single Field inflation to the case of multiple isocurvaton fields with masses of order of Hubble, which are coupled kinetically to the inf…
Curvature Perturbations in Anisotropic Inflation with Symmetry Breaking
Razieh Emami, Hassan Firouzjahi
We study curvature perturbations in the anisotropic inflationary model with a complex scalar field charged under a gauge field in Bianchi I universe. Due to Abelian Higgs me…
Inflation from Charged Scalar and Primordial Magnetic Fields?
Razieh Emami, Hassan Firouzjahi, M. Sadegh Movahed
A model of inflation is presented where the inflaton field is a complex scalar field coupled to a U(1) gauge field. Due to the axial symmetry of the potential, the inflation is dri…
