Published in 2021 at "Physical Review D"

DOI: 10.1103/physrevd.104.125012

Abstract: The violation of the Bell inequality for Dirac fermions is investigated in the cosmological de Sitter spacetime, in the presence of background electromagnetic fields of constant strengths. The orthonormal Dirac mode functions are obtained and… read more here.

Published in 2022 at "Physical Review D"

DOI: 10.1103/physrevd.105.085006

Abstract: We study the vacuum polarisation effects of the Dirac fermionic field induced by a pointlike global monopole located in the cosmological de Sitter spacetime. First we derive the four orthonormal Dirac modes in this background… read more here.
