Induced self-energy on a static scalar charged particle in the spacetime of a global monopole with finite core
D. Barbosa, U. de Freitas, E. R. Bezerra de Mello
We analyze the induced self-energy and self-force on a scalar point-like charged test particle placed at rest in the spacetime of a global monopole admitting a general spherically…
Fermionic current densities induced by magnetic flux in a conical space with a circular boundary
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian +1
We investigate the vacuum expectation value of the fermionic current induced by a magnetic flux in a (2+1)-dimensional conical spacetime in the presence of a circular boundary. On…
Fermionic vacuum polarization by a cosmic string in de Sitter spacetime
E. R. Bezerra de Mello, A. A. Saharian
We investigate the fermionic condensate and the vacuum expectation value of the energy-momentum tensor for a massive spinor field in the geometry of a straight cosmic string on bac…
Vacuum polarization of a massive scalar field in a wormhole spacetime
V. B. Bezerra, E. R. Bezerra de Mello, N. R. Khusnutdinov +1
We calculate the vacuum average value of the field square and the stress-energy tensor of a massive scalar field, with non-minimal coupling to the curvature in the short-throat…
