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 (AdS…
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 form…
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…
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…
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…
Hot spaces with positive cosmological constant in the canonical ensemble: de Sitter solution, Schwarzschild-de Sitter black hole, and Nariai universe
José P. S. Lemos, Oleg B. Zaslavskii
In a space with positive cosmological constant , we consider a black hole surrounded by a heat reservoir at radius and temperature , i.e., we analyze the Schwarzschild-de…
Penrose process in Reissner-Nordström-AdS black hole spacetimes: Black hole energy factories and black hole bombs
Duarte Feiteira, José P. S. Lemos, Oleg B. Zaslavskii
The Penrose process for the decay of electrically charged particles in a Reissner-Nordström-anti-de Sitter black hole spacetime is studied. To extract large quantities of energy on…
Normal modes of Proca fields in AdS spacetime
David Lopes, Tiago V. Fernandes, José P. S. Lemos
The normal modes of Proca field perturbations in -dimensional anti-de Sitter spacetime, AdS for short, with reflective Dirichlet boundary conditions, are obtained exactly. W…
Grand canonical ensemble of a -dimensional Reissner-Nordström black hole in a cavity
Tiago V. Fernandes, José P. S. Lemos
The grand canonical ensemble of a -dimensional Reissner-Nordström black hole space in a cavity is analyzed. The realization of this ensemble is made through the Euclidean path i…
Thermodynamics of five-dimensional Schwarzschild black holes in the canonical ensemble
Rui André, José P. S. Lemos
We study the thermodynamics of a five-dimensional Schwarzschild black hole in the canonical ensemble using York's formalism. Inside a cavity of fixed size and fixed temperature…
