Motion of test particles around an Einstein-dilaton-Gauss-Bonnet black hole in a uniform magnetic field
Romel M. Vargas, M. A. Cuyubamba
In this work, we study the motion of a magnetized particle orbiting a static and spherically symmetric black hole immersed in an external asymptotically uniform magnetic field in E…
Stability of asymptotically de Sitter and anti-de Sitter black holes in regularized Einstein-Gauss-Bonnet theory
M. A. Cuyubamba
The regularized four-dimensional Einstein-Gauss-Bonnet model has been recently proposed in [D. Glavan and C. Lin, Phys. Rev. Lett. \textbf{124}, 081301 (2020)] whose formulation is…
No stable wormholes in Einstein-dilaton-Gauss-Bonnet theory
M. A. Cuyubamba, R. A. Konoplya, A. Zhidenko
In [P. Kanti, B. Kleihaus, J. Kunz, Phys. Rev. Lett. 107, 271101 (2011)] it was shown that the four-dimensional Einstein-dilaton-Gauss-Bonnet theory allows for wormholes without in…
Quasinormal modes and a new instability of Einstein-Gauss-Bonnet black holes in the de Sitter world
M. A. Cuyubamba, R. A. Konoplya, A. Zhidenko
Analysis of time-domain profiles for gravitational perturbations shows that Gauss-Bonnet black holes in a de Sitter world possess a new kind of dynamical instability which does not…
Laval nozzle as an acoustic analogue of a massive field
M. A. Cuyubamba
We study a gas flow in the Laval nozzle, which is a convergent-divergent tube that has a sonic point in its throat. We show how to obtain the appropriate form of the tube, so that…
