Systematic Renormalization of the Effective Theory of Large Scale Structure
Ali Akbar Abolhasani, Mehrdad Mirbabayi, Enrico Pajer
A perturbative description of Large Scale Structure is a cornerstone of our understanding of the observed distribution of matter in the universe. Renormalization is an essential an…
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…
No Large Scale Curvature Perturbations during Waterfall of Hybrid Inflation
Ali Akbar Abolhasani, Hassan Firouzjahi
In this paper the possibility of generating large scale curvature perturbations induced from the entropic perturbations during the waterfall phase transition of standard hybrid inf…
Tachyonic Resonance Preheating in Expanding Universe
Ali Akbar Abolhasani, Hassan Firouzjahi, M. M. Sheikh-Jabbari
In this paper the tachyonic resonance preheating generated from the bosonic trilinear interactions in an expanding Universe is studied. In inflationary model the tr…
