Kaluza-Klein Magnetic Monopole in Five-Dimensional Global Monopole Sapcetime
A. L. Cavalcanti de Oliveira, E. R. Bezerra de Mello
In this paper we present a solution for Kaluza-Klein magnetic monopole in a five-dimensional global monopole spacetime. This new solution is a generalization of previous ones obtai…
Spinor Casimir densities for a spherical shell in the global monopole spacetime
A. A. Saharian, E. R. Bezerra de Mello
We investigate the vacuum expectation values of the energy-momentum tensor and the fermionic condensate associated with a massive spinor field obeying the MIT bag boundary conditio…
Vacuum Polarization of a Charged Massless Fermionic Field by a Magnetic Flux in the Cosmic String Spacetime
J. Spinelly, E. R. Bezerra de Mello
We calculate the vacuum averages of the energy-momentum tensor associated with a massless left-handed spinor fields due to magnetic fluxes on idealized cosmic string spacetime. In…
Vacuum Polarization by a Magnetic Flux in a Cosmic String Background
J. Spinelly, E. R. Bezerra de Mello
In this paper we analyse the vacuum polarization effects due to a magnetic flux on massless fermionic fields in a cosmic string background. Three distinct configurations of magneti…
Strings in de Sitter space
Eugenio R. Bezerra de Mello, Yves Brihaye, Betti Hartmann
We study both global as well as local (Nielsen-Olesen) strings in de Sitter space. While these type of topological defects have been studied in the background of a de Sitter metric…
Reply to "Comment on 'Gravitating Magnetic Monopole in the Global Monopole Spacetime' "
E. R. Bezerra de Mello
In this Reply I present some arguments in favor of the stability of the topological defect composed by global and magnetic monopoles.
