PBHs and GWs from -inflation and NANOGrav 15-year data
Seyed Ali Hosseini Mansoori, Fereshteh Felegray, Alireza Talebian +1
In this paper, we propose a novel mechanism in -inflation to enhance the power spectrum large enough to seed primordial black holes (PBHs) formation. To accomplish th…
Inflation from Multiple Pseudo-Scalar Fields: PBH Dark Matter and Gravitational Waves
Alireza Talebian, Seyed Ali Hosseini Mansoori, Hassan Firouzjahi
We study a model of inflation with multiple pseudo-scalar fields coupled to a gauge field through Chern-Simons interactions. Because of parity violating interactions, one po…
Hessian matrix, specific heats, Nambu brackets, and thermodynamic geometry
Seyed Ali Hosseini Mansoori, Behrouz Mirza, Mohamadreza Fazel
As an extension to our earlier work \cite{Mirza2}, we employ the Nambu brackets to prove that the divergences of heat capacities correspond to their counterparts in thermodynamic g…
Black hole temperature: minimal coupling vs conformal coupling
Mohamadreza Fazel, Behrouz Mirza, Seyed Ali Hosseini Mansoori
In this article, we discuss the propagation of scalar fields in conformally transformed spacetimes with either minimal or conformal coupling. The conformally coupled equation of mo…
