Matter-antimatter (a)symmetry in de Sitter Universe
Jean-Pierre Gazeau, Hamed Pejhan
We investigate the matter-antimatter properties of elementary systems, modeled as free quantum fields, within the global structure of de Sitter spacetime. By leveraging the distinc…

A misleading naming convention: de Sitter `tachyonic' scalar fields
Jean-Pierre Gazeau, Hamed Pejhan
We revisit the concept of de Sitter (dS) 'tachyonic' scalar fields, characterized by discrete negative squared mass values, and assess their physical significance through a rigorou…
