Asymptotics of Quasi-normal Modes for Multi-horizon Black Holes
Abstract: The issue concerning rigorous methods recently developed in deriving the asymptotics of quasi-normal modes is revisited and applied to a generic non rotating multi-horizon black holes solution. Some examples are illustrated and the single horizon cases are also considered. As a result, the asymptotics for large angular momentum parameter is shown to depend on the difference between th...
متن کاملDirac Quasi-Normal Modes in Schwarzschild Black Hole Spacetimes
H. T. Cho Department of Physics, Tamkang University, Tamsui, Taipei, Taiwan, Republic of China (Dated: February 8, 2006) Abstract We evaluate both the massless and the massive Dirac quasi-normal mode frequencies in the Schwarzschild black hole spacetime using the WKB approximation. For the massless case, we find that, similar to those for the integral spin fields, the real parts of the frequenc...
متن کاملQuasi Normal Modes
In this talk we review different applications of quasinormal modes to black hole physics, string theory and thermalisation in quantum field theory. In particular, we describe the the relation between quasi normal modes of AdS black holes and the time scale for thermalisation in strongly coupled, large N conformal field theory. We also discuss the problem of unitarity within this approach.
متن کاملQuasi-normal Modes of Toroidal, Cylindrical and Planar Black Holes in Anti-de Sitter Spacetimes
We study the quasi-normal modes (QNM) of scalar, electromagnetic and gravitational perturbations of black holes in general relativity whose horizons have toroidal, cylindrical or planar topology in an asymptotically anti-de Sitter (AdS) spacetime. The associated quasinormal frequencies describe the decay in time of the corresponding test field in the vicinities of the black hole. In terms of th...
متن کاملHigh frequency quasi-normal modes for black holes with generic singularities II: Asymptotically non-flat spacetimes
The possibility that the asymptotic quasi-normal mode (QNM) frequencies can be used to obtain the Bekenstein-Hawking entropy for the Schwarzschild black hole — commonly referred to as Hod’s conjecture — has received considerable attention. To test this conjecture, using monodromy technique, attempts have been made to analytically compute the asymptotic frequencies for a large class of black hol...
