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 vacuum polarization in dS spacetime with a compactified cosmic string
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
We study the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a massive spinor field in the de Sitter (dS) spacetime including an…
Relativistic quantum oscillators in the global monopole spacetime
E. A. F. Bragança, R. L. L. Vitória, H. Belich +1
We investigated the effects of the global monopole spacetime on the Dirac and Klein-Gordon relativistic quantum oscillators. In order to do this, we solve the Dirac and Klein-Gordo…
Vacuum expectation value of the energy-momentum tensor in a higher dimensional compactified cosmic string spacetime
E. A. F. Bragança, H. F. Santana Mota, E. R. Bezerra de Mello
The main objective of this paper is to analyze the vacuum expectation value (VEV) of the energy-momentum tensor (EMT) associated with a charged scalar quantum field in a high-dimen…
