Charged scalar boson in Melvin universe

L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +2

This work investigates the dynamics of a charged scalar boson in the Melvin universe by solving the Klein-Gordon equation with minimal coupling in both inertial and non-inertial fr…

Black holes as gravitational mirrors

L. C. N. Santos, F. M. da Silva, C. R. Muniz +1

Retrolensing is a gravitational lensing effect in which light emitted by a background source is deflected by a black hole and redirected toward the observer after undergoing nearly…

Cornell and Coulomb potentials in the double defect spacetime

L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +1

We analyze the quantum dynamics of a scalar field in a spacetime incorporating dual topological defects, specifically a cosmic string and a global monopole. Utilizing a generalized…

Bound and Scattering States in a Spacetime with Dual Topological Defects: Cosmic String and Global Monopole

L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +1

This paper explores the relativistic quantum motion of scalar bosons in the presence of mixed topological defects: cosmic strings and global monopoles. The Klein-Gordon equation wi…

Regular black holes from Kiselev anisotropic fluid

Luis C. N. Santos

In this paper, we investigate a generalization of Kiselev black holes by introducing a varying equation of state parameter for the anisotropic fluid surrounding the black hole. We…
