Tail diversity from inflation
Sina Hooshangi, Mohammad Hossein Namjoo, Mahdiyar Noorbala
The tail of the distribution of primordial fluctuations (corresponding to the likelihood of realization of large fluctuations) is of interest, from both theoretical and observation…
The Effective Field Theory of Large Scale Structures of a Fuzzy Dark Matter Universe
Hamed Manouchehri Kousha, Sina Hooshangi, Aliakbar Abolhasani
Ultra-light scalar fields and their non-interacting class, the so-called fuzzy dark matter (FDM), are candidates for dark matter, introduced to solve the small-scale problems of th…
Multiple Field Ultra Slow Roll Inflation: Primordial Black Holes From Straight Bulk And Distorted Boundary
Sina Hooshangi, Alireza Talebian, Mohammad Hossein Namjoo +1
We study a model of two-field ultra-slow-roll (USR) inflation bounded by a curve in the field space. Curvature perturbations and non-Gaussianities can be enhanced both during the U…
Rare Events Are Nonperturbative: Primordial Black Holes From Heavy-Tailed Distributions
Sina Hooshangi, Mohammad Hossein Namjoo, Mahdiyar Noorbala
In recent years it has been noted that the perturbative treatment of the statistics of fluctuations may fail to make correct predictions for the abundance of primordial black holes…
