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…

Rotating Thin Shells in Einstein-Gauss-Bonnet Gravity

João D. Álvares, Tiago V. Fernandes

A rotating metric solution in Einstein-Gauss-Bonnet gravity with a negative cosmological constant was recently found in the Chern-Simons point. We construct a rotating thin shell g…

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…

Quasinormal modes of a Proca field in Schwarzschild-AdS spacetime via the isomonodromy method

Julián Barragán Amado, Tiago V. Fernandes, David C. Lopes

We consider Proca field perturbations in a five-dimensional Schwarzschild-anti-de Sitter (Schwarzschild-AdS) black hole geometry. Using the vector spherical harmonic (VSH) me…
