Looking at the Gregory-Laflamme instability through quasi-normal modes
R. A. Konoplya, Keiju Murata, Jiro Soda +1
We study evolution of gravitational perturbations of black strings. It is well known that for all wavenumber less than some threshold value, the black string is unstable against sc…
(In)stability of D-dimensional black holes in Gauss-Bonnet theory
R. A. Konoplya, A. Zhidenko
We make an extensive study of evolution of gravitational perturbations of D-dimensional black holes in Gauss-Bonnet theory. There is an instability at higher multi-poles and…
Quantum corrections to the noncommutative kink
R. A. Konoplya, D. V. Vassilevich
We calculate quantum corrections to the mass of noncommutative phi^4 kink in (1+1) dimensions for intermediate and large values of the noncommutativity parameter theta. All one-loo…
Perturbations of Schwarzschild black holes in laboratories
E. Abdalla, R. A. Konoplya, A. Zhidenko
It is well-known that the perturbations of Schwarzschild black holes are governed by a wave equation with some effective potential. We consider perturbations of a gas in a tube cal…
Particle motion around magnetized black holes: Preston-Poisson space-time
R. A. Konoplya
We analyze motion of massless and massive particles around black holes immersed in an asymptotically uniform magnetic field and surrounded by some mechanical structure, which provi…
