Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics
C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…
Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole
C. F. S. Pereira, H. Belich, A. R. Soares +3
In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…
Numerical study of non-relativistic quantum systems and small oscillations induced in a helically twisted geometry
C. F. S. Pereira, R. L. L. Vitória, A. R. Soares +3
We investigate bound states of a non-relativistic scalar particle in a three-dimensional helically twisted (torsional) geometry, considering both the free case and the presence of…
Light deflection and gravitational lensing effects in acoustic black-bounce spacetime
C. F. S. Pereira, A. R. Soares, M. V. de S. Silva +2
In the present work, we analyze the gravitational deflection for a light beam in the weak and strong field regimes for the gravitational analogue geometry of an acoustic black hole…
Light deflection and gravitational lensing effects inspired by loop quantum gravity
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória +2
In the present work, we theoretically investigate light deflection in the weak and strong field regimes for two regular spacetimes with corrections from loop quantum gravity. We tr…
