Fermionic vacuum polarization by a cylindrical boundary in the cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian +1
The vacuum expectation values of the energy--momentum tensor and the fermionic condensate are analyzed for a massive spinor field obeying the MIT bag boundary condition on a cylind…
Fermionic vacuum densities in higher-dimensional de Sitter spacetime
E. R. Bezerra de Mello, A. A. Saharian
Fermionic condensate and the vacuum expectation values of the energy-momentum tensor are investigated for twisted and untwisted massive spinor fields in higher-dimensional de Sitte…
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…
