Quasinormal modes of Proca and Maxwell fields in -dimensional Schwarzschild-AdS black holes
David C. Lopes, Tiago V. Fernandes, José P. S. Lemos
Proca and Maxwell fields in -dimensional Schwarzschild black holes with anti-de Sitter (AdS) asymptotics are investigated through their linear perturbations and associated quasi…
Recursive Penrose processes in electrically charged black hole spacetimes: Backreaction and energy extraction
Duarte Feiteira, José P. S. Lemos, Oleg B. Zaslavskii
We study a recursive Penrose process and the energy extraction for the decay of electrically charged particles in a Reissner-Nordström black hole spacetime with anti-de Sitter (Ad…
The canonical ensemble of a self-gravitating matter thin shell in AdS
Tiago V. Fernandes, Francisco J. Gandum, José P. S. Lemos
We build the canonical ensemble of a hot self-gravitating matter thin shell in anti-de Sitter (AdS) space by finding its partition function through the Euclidean path integral appr…
Gibbons-Hawking action for electrically charged black holes in the canonical ensemble and Davies' thermodynamic theory of black holes
Tiago V. Fernandes, José P. S. Lemos
We establish the connection between the Gibbons-Hawking Euclidean path integral approach applied to the canonical ensemble of a Reissner-Nordström black hole and the thermodynamic…
Canonical ensemble of a -dimensional Reissner-Nordström black hole in a cavity
Tiago V. Fernandes, José P. S. Lemos
We construct the canonical ensemble of a -dimensional Reissner-Nordström black hole spacetime in a cavity surrounded by a heat reservoir through the Euclidean path integral for…
Penrose and super-Penrose energy extraction from a Reissner-Nordström black hole spacetime with a cosmological constant through the BSW mechanism: Full story
Duarte Feiteira, José P. S. Lemos, Oleg B. Zaslavskii
The Penrose process, a process that transfers energy from a black hole to infinity, together with the BSW mechanism, which uses collisions of ingoing particles at the event horizon…
