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…
Revisiting black holes surrounded by cloud and fluid of strings in general relativity
Luis Cesar Nunes dos Santos
This paper revisits black hole solutions surrounded by clouds and fluids of strings within the framework of general relativity. We introduce a generalized equation of state for a f…
