Chaotic motion of particles around a Schwarzschild black hole in a swirling electromagnetic background
Wenbin Li, Yu-Qi Lei, Xian-Hui Ge
We investigate the particle motion around a Schwarzschild black hole immersed in a swirling Bertotti-Robinson-Bonnor-Melvin background. This spacetime provides a physically well-mo…
Spin-Hair Induced Chaos of Spinning Test Particles in Rotating Hairy Black Holes
Surojit Dalui, Xian-Hui Ge
We investigate the finite-time instability of massive spinning test particles around a rotating hairy black hole generated through gravitational decoupling. The particle motion is…
Analytical solution of traversable wormholes in the presence of positive cosmological constant
Rajesh Karmakar, Xian-Hui Ge
The construction of traversable wormholes (WHs) with a cosmological constant, , introduces significant challenges and leads to non-trivial modifications of the spacetime geomet…
Massive vector field perturbations in the Schwarzschild spacetime from supersymmetric gauge theory
Xian-Hui Ge, Masataka Matsumoto, Kilar Zhang
We unify the dynamics of massive vector (Proca) fields in Schwarzschild spacetime with supersymmetric gauge theories through the Seiberg-Witten/quasinormal mode (SW/QNM) duality. B…
