Finite temperature fermionic condensate and currents in topologically nontrivial spaces
S. Bellucci, E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature fermionic condensate and the expectation values of the charge and current densities for a massive fermion field in a spacetime background with…
Fermionic vacuum polarization in compactified cosmic string spacetime
S. Bellucci, E. R. Bezerra de Mello, A. de Padua +1
We investigate the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a charged massive fermionic field in the geometry of a cosmic…
Electromagnetic two-point functions and the Casimir effect in Friedmann-Robertson-Walker cosmologies
S. Bellucci, A. A. Saharian
We evaluate the two-point functions of the electromagnetic field in (D+1) -dimensional spatially flat Friedmann-Robertson-Walker universes with a power-law scale factor, assuming t…
Electromagnetic two-point functions and Casimir densities for a conducting plate in de Sitter spacetime
A. A. Saharian, A. S. Kotanjyan, H. A. Nersisyan
We evaluate the two-point function for the electromagnetic field tensor in -dimensional de Sitter spacetime assuming that the field is prepared in Bunch-Davies vacuum state.…
Fermionic current induced by magnetic flux in compactified cosmic string spacetime
E. R. Bezerra de Mello, A. A. Saharian
In this paper, we investigate the fermionic current densities induced by a magnetic flux running along the idealized cosmic string in a four-dimensional spacetime, admitting that t…
Fermionic vacuum polarization by a cosmic string in anti-de Sitter spacetime
E. R. Bezerra de Mello, E. R. Figueiredo Medeiros, A. A. Saharian
In this paper we investigate the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor, associated with a massive fermionic field, induced…
