Bubble nucleation and inflationary perturbations
Hassan Firouzjahi, Sadra Jazayeri, Asieh Karami +1
In this work we study the imprints of bubble nucleation on primordial inflationary perturbations. We assume that the bubble is formed via the tunneling of a spectator field from th…

Effective field theory of statistical anisotropies for primordial bispectrum and gravitational waves
Tahereh Rostami, Asieh Karami, Hassan Firouzjahi
We present the effective field theory studies of primordial statistical anisotropies in models of anisotropic inflation. The general action in unitary gauge is presented to calcula…
