Quasinormal modes of maximally charged black holes.
A new algorithm for computing the accurate values of quasinormal frequencies of extremal Reissner-Nordström black holes is presented. The numerically computed values are consistent with the values earlier obtained by Leaver and those obtained through the WKB method. Our results are more precise than other results known to date. We also find a curious fact that the resonant frequencies of gravit...
متن کاملQuasinormal modes of stringy black holes
String theory is a promising candidate for a fundamental quantum theory of all interactions including Einstein gravity. Some solutions in string theory can be interpreted as black holes. Using the semi-analytic method and WKB method,the quasinormal modes(QNMs)of 1+1 dimensional black hole in string theory are studied.The QNMs of 1+3 dimensional black hole in string theory are also calculated th...
متن کاملQuasinormal modes of black holes and black branes
Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical gravitational backgrounds involving black holes or branes naturally lead to quasinormal modes. The analysis and classification of the quasinormal spectra requires solving non-Hermitian eigenvalue problems for the associated linear differential equations. Within the recently developed gauge-gravity duality, these...
متن کاملDirac quasinormal modes of charged black holes in higher dimensions
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...
متن کاملAbout the Signiicance of Quasinormal Modes of Black Holes
Quasinormal modes have played a prominent role in the discussion of perturbations of black holes, and the question arises whether they are as signiicant as normal modes are for self adjoint systems, such as harmonic oscillators. They can be signiicant in two ways: Individual modes may dominate the time evolution of some perturbation, and a whole set of them could be used to completely describe ...
