Systematics of Adiabatic Modes: Flat Universes
Enrico Pajer, Sadra Jazayeri
Adiabatic modes are cosmological perturbations that are locally indistinguishable from a (large) change of coordinates. At the classical level, they provide model independent solut…
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…
Primordial anisotropies from cosmic strings during inflation
Sadra Jazayeri, Alireza Vafaei Sadr, Hassan Firouzjahi
In this work we study the imprints of a primordial cosmic string on inflationary power spectrum. Cosmic string induces two distinct contributions on curvature perturbations power s…
