Cosmic string configuration in a five dimensional Brans-Dicke theory
V. B. Bezerra, C. N. Ferreira, G. de A. Marques
We consider a scalar field interaction with a cosmic string configuration in a flat 3-brane. The origin of this field is given by a compactification mechanism in the context of a 5…
Corrections to the fine structure constant in higher dimensional global monopole spacetime
Geusa de A. Marques, V. B. Bezerra
In this paper we use the Generalized Uncertainty Principle in order to obtain the corrections to the fine structure constant in (D+1)-dimensional global monopole spacetime. The res…
Hydrogen atom in the gravitational fields of topological defects
Geusa de A. Marques, V. B. Bezerra
We consider a hydrogen atom in the background spacetimes generated by an infinitely thin cosmic string and by a point-like global monopole. In both cases, we find the solutions of…
Landau Levels in the Presence of Topological Defects
G. de A. Marques, Claudio Furtado, V. B. Bezerra +1
We study the Landau levels associated with electrons moving in a magnetic field in the presence of a continuous distribution of disclinations, a magnetic screw dislocation and a di…
