The generalized second law for Kerr-Taub-NUT black holes perturbed by test field
Koray Düztaş, Ahmet Cem Erdoğan
We evaluate the variations in the area and the entropy of Kerr-Taub-NUT black holes perturbed by bosonic and fermionic test fields. We demonstrate that the critical frequency for a…
Dual entropy gain by radiation at the zero temperature limit
Koray Düztaş
Recently we have demonstrated that black hole radiation can be smoothly extended to the zero-temperature limit. Here we analyse entropy variations at the zero temperature limit and…
Self energy in Kerr-Sen space-time incorporated to overspinning and overcharging problems
Koray Düztaş
Previous attempts to overspin or overcharge Kerr-Sen black holes have been incomplete, as they neglect back-reaction effects. In this study, we incorporate the self-energy of pertu…
Can the induced increase in the angular velocity prevent the overspinning of BTZ black holes?
Koray Düztaş
Previously we showed that nearly extremal Bañados-Teitelboim-Zanelli (BTZ) black holes can be overspun by test bodies and fields, following the work of Rocha and Cardoso for the ex…
