Quasinormal Modes of Near Extremal Black Branes
We find quasinormal modes of near extremal black branes by solving a singular boundary value problem for the Heun equation. The corresponding eigenvalues determine the dispersion law for the collective excitations in the dual strongly coupled N = 4 SYM at finite temperature. In memory of Aleksandr Sergeevich Vshivtsev
متن کاملAsymptotic quasinormal modes of a coupled scalar field in the Gibbons-Maeda dilaton spacetime
The study of quasinormal modes in a black hole background spacetime has a long history [1]-[19]. It is shown that their frequencies and damping times are entirely fixed by the black hole parameters and independent of the initial perturbations. Therefore, it is certain that quasinormal modes carry the characteristic information about a black hole and it can provide a new and direct way for astro...
متن کاملScalar gravitational perturbations and quasinormal modes in the five dimensional Schwarzschild black hole
We calculate the quasinormal modes (QNMs) for gravitational perturbations of the Schwarzschild black hole in the five dimensional (5D) spacetime with a continued fraction method. As shown by Kodama and Ishibashi, the gravitational perturbations of higher-dimensional (higher-D) Schwarzschild black holes can be divided into three decoupled classes, namely scalar-gravitational, vectorgravitational...
متن کاملQuasinormal 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...
