Fermionic vacuum polarization by a composite topological defect in higher-dimensional space-time
E. R. Bezerra de Mello, A. A. Saharian
We investigate the vacuum polarization effects associated with a charged massless spin-1/2 field in a higher-dimensional space-time, induced by a composite topological defect. The…
Fermionic vacuum polarization in higher-dimensional global monopole spacetime
E. R. Bezerra de Mello
In this paper we analyse the vacuum polarization effects associated with a massless fermionic field in a higher-dimensional global monopole spacetime in the "braneworld" scenario.…
Polarization of the fermionic vacuum by a global monopole with finite core
E. R. Bezerra de Mello, A. A. Saharian
We study the vacuum polarization effects associated with a massive fermionic field in a spacetime produced by a global monopole considering a nontrivial inner structure for it. In…
Electromagnetic Casimir densities induced by a conducting cylindrical shell in the cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian
We investigate the renormalized vacuum expectation values of the field square and the energy-momentum tensor for the electromagnetic field inside and outside of a conducting cylind…
Electrostatic self-interaction in the spacetime of a global monopole with finite core
E. R. Bezerra de Mello, A. A. Saharian
In this paper we calculate the induced electrostatic self-energy and self-force for an electrically charged particle placed at rest in the spacetime of a global monopole admitting…
Vacuum Polarization in the Presence of Magnetic Flux at Finite Temperature in the Cosmic String Background
J. Spinelly, E. R. Bezerra de Mello
In this paper we analyse the vacuum polarization effect associated with the charged massless scalar field, in the presence of magnetic flux at finite temperature, in the cosmic str…
