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…

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…

Vacuum zero point energy of self-interacting quantum fields in dS background
Hassan Firouzjahi, Haidar Sheikhahmadi
We consider self-interacting scalar fields with a conformal coupling in the dS background and study the quantum corrections from bubble loop diagrams. Incorporating the perturbativ…
