Finite temperature fermionic charge and current densities induced by a cosmic string with magnetic flux
A. Mohammadi, E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature expectation values of the charge and current densities for a massive fermionic field with nonzero chemical potential, , in the geometry of…
Vacuum currents induced by a magnetic flux around a cosmic string with finite core
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian +1
We evaluate the Hadamard function and the vacuum expectation value of the current density for a massive complex scalar field in the generalized geometry of a straight cosmic string…
Induced vacuum bosonic current by magnetic flux in a higher dimensional compactified cosmic string spacetime
E. A. F. Bragança, H. F. Santana Mota, E. R. Bezerra de Mello
In this paper, we analyse the bosonic current densities induced by a magnetic flux running along an idealized cosmic string in a high-dimensional spacetime, admitting that the coor…
Induced vacuum currents in anti-de Sitter space with toral dimensions
E. R. Bezerra de Mello, A. A. Saharian, V. Vardanyan
We investigate the Hadamard function and the vacuum expectation value of the current density for a charged massive scalar field on a slice of anti-de Sitter (AdS) space described i…
Casimir effect in hemisphere capped tubes
E. R. Bezerra de Mello, A. A. Saharian
In this paper we investigate the vacuum densities for a massive scalar field with general curvature coupling in background of a (2+1)-dimensional spacetime corresponding to a cylin…
Induced fermionic currents in de Sitter spacetime in the presence of a compactified cosmic string
A. Mohammadi, E. R. Bezerra de Mello, A. A. Saharian
We investigate the vacuum fermionic currents in the geometry of a compactified cosmic string on background of de Sitter spacetime. The currents are induced by magnetic fluxes runni…
Abelian-Higgs strings in Rastall gravity
Eugenio R. Bezerra de Mello, Julio C. Fabris, Betti Hartmann
In this paper we analyze Abelian-Higgs strings in a phenomenological model that takes quantum effects in curved space-time into account. This model, first introduced by Rastall, ca…
