Holographic conductivity of zero temperature superconductors
R. A. Konoplya, A. Zhidenko
Using the recently found by G. Horowitz and M. Roberts (arXiv:0908.3677) numerical model of the ground state of holographic superconductors (at zero temperature), we calculate the…
Gravitational stability of simply rotating Myers-Perry black holes: tensorial perturbations
Hideo Kodama, R. A. Konoplya, Alexander Zhidenko
We study the stability of asymptotically flat black holes rotating in a single two-plane against tensor-type gravitational perturbations. The extensive search of quasino…
Linear perturbations of black holes: stability, quasi-normal modes and tails
Alexander Zhidenko
Black holes have their proper oscillations, which are called the quasi-normal modes. The proper oscillations of astrophysical black holes can be observed in the nearest future with…
Gravitational instability of simply rotating AdS black holes in higher dimensions
Hideo Kodama, R. A. Konoplya, A. Zhidenko
We study the stability of AdS black hole holes rotating in a single two plane for tensor-type gravitational perturbations in space-time dimensions. First, by an analytic me…
