Tidal dynamics and stellar disruption in charged Kalb-Ramond black holes in nonlinear electrodynamics
Ednaldo L. B. Junior, Herlan N. Lemos, Marcos V. de S. Silva
We investigate tidal forces, geodesic deviation, and tidal disruption in the black hole spacetime described by the Kalb-Ramond-ModMax solution, where electromagnetic nonlinearity i…

Scalar and spinor fields in gravitating cosmic string spacetimes
Marcos Silva, Azadeh Mohammadi
We study the scattering behavior of scalar and spinor fields in the background of a gravitating cosmic string spacetime. The model explored here for the background vortex is non-ab…

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…
