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…
δN Formalism in Anisotropic Inflation and Large Anisotropic Bispectrum and Trispectrum
Ali Akbar Abolhasani, Razieh Emami, Javad T. Firouzjaee +1
We present a consistent δN formalism for curvature perturbations in anisotropic cosmological backgrounds. We employ our δN formalism to calculate the power spectrum, the bispectrum…
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…
