Beyond de Sitter: Longitudinal-Mode Instabilities and Spectral Evolution of Massive Vector Fields with Non-Minimal Curvature Coupling during Inflation
Ehsan Momeni, Fatimah Shojai
We investigate the inflationary dynamics of a spectator massive vector field with a non-minimal curvature coupling in de Sitter (dS) and quasi-de Sitter (qdS) backgrounds, focusing…
Observational Constraints on Chaplygin Gas Models in Non-Minimally Coupled Power Law Gravity with Quasars
Nakul Aggarwal, Ali Pourmand, Fatimah Shojai +1
In the framework of gravity, where gravity emerges from non-metricity , we explore the cosmological implications of its non-minimal coupling to matter. Inspired by the re…
Geodetic precession and shadow of quantum extended black holes
Reza Saadati, Fatimah Shojai
We study the circular motion of massive and massless particles in a recently proposed quantum-corrected Schwarzschild black hole in loop quantum gravity. This solution is supposed…
Trans-Planckian Effect in Cosmology
S. Cheraghchi, F. Shojai, M. H. Abbassi
Apart from the assumption that the inflation started at an infinite time in the past, the more realistic initial state of the quantum fluctuations is described by a mixed quantum s…
On the gravitational collapse in 4-dimensional Einstein-Gauss-Bonnet gravity
R. Hassannejad, A. Sadeghi, F. Shojai
In this paper, we treat 4-dimensional Einstein-Gauss-Bonnet gravity as general relativity with an effective stress-energy tensor. We will study the modified Oppenheimer-Snyder-Datt…
Constraining Generalized Chaplygin Gas in Non-Minimally Coupled Cosmology using Quasars and Data
Nakul Aggarwal, Ali Pourmand, Fatimah Shojai +1
In the current framework of Einstein's equations in general relativity (GR), gravity is described by the spacetime curvature. However, there are other descriptions where the origin…
