Evolution of perturbations of squashed Kaluza-Klein black holes: escape from instability (2008)
Ishihara, Hideki, Kimura, Masashi, Konoplya, Roman A., Murata, Keiju, Soda, Jiro, Zhidenko, Alexander
The squashed Kaluza-Klien (KK) black holes differ from the Schwarzschild black holes with asymptotic flatness or the black strings even at energies for which the KK modes are not excited yet, so that...

High Overtones of Dirac Perturbations of a Schwarzschild Black Hole and the Area Spectrum of Quantum Black Holes
Castello-Branco,KarlĂșcio H. C., Konoplya,Roman A., Zhidenko,Alexander
We find high overtones of the Dirac quasi-normal (QN) spectrum of a Schwarzschild black hole (Sbh), by Leaver's method. At high overtones, the spacing of the imaginary part of the QN spectrum is...
