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…

Scattering of kinks in the $B φ^{4}$ model

Mohammad Mohammadi, Ehsan Momeni

In this study, based on the $φ^{4}$ model, a new model (called the $B φ^{4}$ model) is introduced in which the potential form for the values of the field whose magnitudes are greater th…
