The Euclidean Scalar Green Function in the Five-Dimensional Kaluza-Klein Magnetic Monopole Spacetime
E. R. Bezerra de Mello
In this paper we present, in a integral form, the Euclidean Green function associated with a massless scalar field in the five-dimensional Kaluza-Klein magnetic monopole superposed…
Comment to "Fine structure constant in the spacetime of a cosmic string"
E. R. Bezerra de Mello
In the paper Phys. Lett. B614 (2005), 140-142, F. Nasseri shows that the values of the fine structure constant reduces due to the presence of a cosmic string. In this comment I wan…
Casimir Densities for a Massive Fermionic Quantum Field in a Global Monopole Background with Spherical Boundary
A. A. Saharian, E. R. Bezerra de Mello
We investigate the vacuum expectation value of the energy-momentum tensor associated with a massive fermionic field obeying the MIT bag boundary condition on a spherical shell in t…
Vacuum Polarization of a Massless Scalar Field in the Background of a Global Monopole with Finite Core
J. Spinelly, E. R. Bezerra de Mello
In this paper we analyze the vacuum polarization effects of a massless scalar field in the background of a global monopole considering a inner structure to it. Specifically we inve…
