Dirac quasinormal modes of charged black holes in higher dimensions
نویسنده
چکیده
In this work we study the Dirac quasinormal modes of higher dimensional charged black holes. Higher dimensional Reissner-Nördstrom type black holes as well as charged black holes in Einstein GaussBonnet theories are studied for Fermionic perturbations using WKB methods. A comparative study of the quasinormal modes in the two different theories of gravity has been performed. The beahviour of the frequencies with the variation of black hole parameters as well as with the variation of spacetime dimensions are done. We also study the large multipole number limit of the black hole potential in order to look for an analytic expression for the frequencies. PACS : 04.70.Dy, 04.60.-m Email: [email protected]

متن کاملQuasinormal Modes of Maximally Charged RN Black Holes and the Search for a Quantum Theory of Gravity
In the context of searching for a quantum theory of gravity, the quasinormal modes of black holes has become a promising area of study that may link a quantum theory of gravity with classical general relativity. Of special interest are the asymptotic real values of the quasinormal frequencies, which have recently been shown to converge to an analytically predicted value. In this paper, we will ...
متن کاملObject picture of quasinormal ringing on the background of small Schwarzschild Anti-de Sitter black holes
We investigated the evolution of a scalar field propagating in small Schwarzschild Anti-de Sitter black holes. The imaginary part of the quasinormal frequency decreases with the horizon size and the real part of the quasinormal frequency keeps nearly as a constant. The object-picture clarified the question about on the quasinormal modes for small Anti-de Sitter black holes. Dependence of quasin...

We compute characteristic (quasinormal) frequencies corresponding to decay of a massive charged scalar field in a Reissner-Nordstrom black hole background. It proves that, contrary to the behavior at very late times, at the stage of quasinormal ringing the neutral perturbations will damp slower than the charged ones. In the limit of the extremal black hole the damping rate of charged and neutra...
متن کاملQuasinormal modes of nearly extreme Reissner-Nordström black holes.
We present detailed calculations of the quasinormal modes of ReissnerNordström black holes. While the first few, slowly damped, modes depend on the charge of the black hole in a relatively simple way, we find that the rapidly damped modes show several peculiar features. The higher modes generally spiral into the value for the extreme black hole as the charge increases. We also discuss the possi...
