Electromagnetic effects on dynamics of string fluid and information paradox in rainbow gravity

U Sheikh, S Arshad - Annals of Physics, 2022 - Elsevier
This work is devoted to studying the effects of electric field intensity on collapsing anisotropic
string fluid in Rainbow gravity. The Einstein field equations are modified and solved for the …

Dynamics of charged string cloud collapse in rainbow gravity

U Sheikh, S Arshad, M Arshad - International Journal of Geometric …, 2022 - World Scientific
This work will proceed to examine the dynamics of collapsing charged string cloud in a
spherically symmetric rainbow metric. This is the framework that allows new stars and …

Properties of black hole vortex in Einstein's gravity

FCE Lima, ARP Moreira, CAS Almeida - The European Physical Journal …, 2023 - Springer
We investigate the influence of the matter field and the gauge field on the metric functions of
the AdS 3 spacetime of the Maxwell–Higgs model. By considering a matter field with a …

Black hole surrounded by a magnetic vortex in gravity

FCE Lima, CAS Almeida - arXiv preprint arXiv:2501.02712, 2025 - arxiv.org
Modified Gravity Theories (MGTs) are extensions of General Relativity (GR) in its standard
formulation. In light of this premise, we employ Heisenberg's non-perturbative approach to …
