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…
