Finite temperature fermionic condensate and energy-momentum tensor in cosmic string spacetime
W. Oliveira dos Santos, E. R. Bezerra de Mello
Here we analyze the expectation value of the fermionic condensate and the energy-momentum tensor associated with a massive charged fermionic quantum field with a nonzero chemical p…
Vacuum effects induced by a plate in de Sitter spacetime in the presence of a cosmic string
W. Oliveira dos Santos, E. R. Bezerra de Mello
In this paper we investigate the vacuum expectation values of the field squared and the energy-momentum tensor associated to a charged massive scalar quantum field in a -dim…
Induced current by a cosmic string and a brane in high-dimensional AdS spacetime
W. Oliveira dos Santos, E. R. Bezerra de Mello
In this paper we investigate the bosonic current induced by a brane and a magnetic flux running along the idealized cosmic string in a -dimensional anti-de Sitter (AdS) back…
Vacuum polarization induced by a cosmic string and a brane in AdS spacetime
W. Oliveira dos Santos, E. R. Bezerra de Mello
In this paper we investigate the vacuum polarization effects associated to a charged quantum massive scalar field on a -dimensional anti-de Sitter background induced by a ma…
