Universality in quasinormal modes of a magnetized black hole
Marcos R. Ribeiro, Eveling C. Ribeiro, Kai Lin +1
In this work, we investigate the linear stability of a magnetized Einstein-Maxwell solution describing a static, axially symmetric black hole (BH) immersed in a uniform magnetic fi…

Nielsen complexity with multiple cost factors
Marcos Rios Ribeiro, Diego Trancanelli
We investigate Nielsen's geometric approach to quantum complexity in the presence of multiple cost factors, extending the standard framework where a single penalty distinguishes ea…

Stability of the spacetime of a magnetized compact object
Eveling C. Ribeiro, L. Formigari, Marcos R. Ribeiro +5
We investigate the stability of scalar perturbations around a magnetized stationary compact object in General Relativity. The considered object is one of the simplest exact solutio…
