RG-Flow Renormalized One-Loop Corrections to the Power Spectrum in USR Inflation
Haidar Sheikhahmadi, Amin Nassiri-Rad
The nature of one-loop corrections to long-wavelength CMB-scale modes in single-field inflation models with an intermediate ultra-slow-roll (USR) phase remains a subject of active…
Kerr black hole in presence of force-free magnetic field
Haidar Sheikhahmadi
We extend the study of force-free magnetospheres from non-rotating to rotating black holes \cite{Sheikhahmadi} and investigate the influence of a force-free magnetic field on the g…
Stochastic Inflation with Interacting Noises
Amin Nassiri-Rad, Haidar Sheikhahmadi, Hassan Firouzjahi
Stochastic formalism is a powerful tool to calculate the cosmological correlators non-perturbatively. However, it requires the initial data for the amplitude of the noise on…
Remove point-mass concept-remove singularities from GR
Yousef Sobouti, Haidar Sheikhahmadi
Singularities in Newton's gravitation, in general relativity (GR), in Coulomb's law, and elsewhere in classical physics, stem from two ill conceived assumptions: a) there are point…
