CMB statistical anisotropies of classical and quantum origins
Xingang Chen, Razieh Emami, Hassan Firouzjahi +1
We examine the impact of different anisotropic relics on inflation, in particular the predictions on the density perturbations. These relics can be the source of the large scale an…
Statistical Anisotropies in Gravitational Waves in Solid Inflation
Mohammad Akhshik, Razieh Emami, Hassan Firouzjahi +1
Solid inflation can support a long period of anisotropic inflation. We calculate the statistical anisotropies in the scalar and tensor power spectra and their cross-correlation in…
Scalar-Tensor Anti-Cross-Correlation does not Help to Reconcile the Tension between BICEP2 and Planck
Razieh Emami, Hassan Firouzjahi, Yi Wang
We examine the recent proposal [1] that the anti-cross-correlation of the scalar and tensor primordial fluctuations reconciles the tension between BICEP2 and Planck observations. W…
The TT, TB, EB and BB correlations in anisotropic inflation
Xingang Chen, Razieh Emami, Hassan Firouzjahi +1
The ongoing and future experiments will measure the B-mode from different sky coverage and frequency bands, with the potential to reveal non-trivial features in polarization map. I…
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…
