Optical properties of gravitating strings
Marcos Silva, Azadeh Mohammadi
We study the optical properties of gravitating Abelian-Higgs cosmic strings and compare them with those of the idealized infinitely thin string. We analyze the structure of the cor…
Scalar and spinor fields in gravitating cosmic string spacetimes
Marcos Silva, Azadeh Mohammadi
We study the scattering behavior of scalar and spinor fields in the background of a gravitating cosmic string spacetime. The model explored here for the background vortex is non-ab…
Finite temperature Casimir effect for a spinor field in cosmic dispiration spacetime
Joás Venâncio, Herondy Mota, Azadeh Mohammadi
This study explores the finite temperature Casimir effect for a massive spinor field in cosmic dispiration spacetime, formed by the combination of a cosmic string and a screw dislo…
Vacuum bosonic currents induced by a compactified cosmic string in dS background
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
In this paper, we investigate the vacuum bosonic currents in the geometry of a compactified cosmic string in the background of the de Sitter spacetime. The currents are induced by…
Induced fermionic current at finite temperature
Eugênio R. Bezerra de Mello, Aram A. Saharian, Azadeh Mohammadi
Here we analyze the finite temperature expectation values of the charge and current densities for a massive fermionic quantum field with nonzero chemical potential, , induced by…
