Gravitational-wave signatures of spinning particles around rotating hairy black holes
Surojit Dalui, Xian-Hui Ge
We study how the spin of a compact secondary and a gravitational-decoupling deformation of the Kerr geometry are imprinted on gravitational waves from strong-field eccentric motion…
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 with a cosmological constant, , introduces significant challenges and leads to non-trivial modifications of the spacetime geometry. In…
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…
Duality between Seiberg-Witten Theory and Black Hole Superradiance
Xian-Hui Ge, Masataka Matsumoto, Kilar Zhang
The newly established Seiberg-Witten (SW)/Quasinormal Modes (QNM) correspondence offers an efficient analytical approach to calculate the QNM frequencies, which was only available…
Thermo-electric Transport of Dyonic Gubser-Rocha Black Holes
Xian-Hui Ge, Zhaojie Xu
We study the thermo-electric transport coefficients of an extended version of the Gubser-Rocha model. After reviewing the two relaxation time model from holography and studying the…
