No-go theorem for spontaneous vectorization
Hsu-Wen Chiang, Sebastian Garcia-Saenz, Aofei Sang
Generalized vector-tensor theories of gravity have drawn attention for admitting hairy black hole solutions, thereby circumventing the standard no-hair theorems. It remains an open…
Collisional Penrose process of extended test particles near an extremal Kerr black hole
Aofei Sang, Jie Jiang, Ming Zhang
We investigate the collisional Penrose process of extended test particles near extremal Kerr black holes using the pole-dipole-quadrupole approximation. We analyze the motion of th…
Strong Cosmic Censorship in Einstein-Maxwell-Scalar-Gauss-Bonnet Theory
Aofei Sang, Jie Jiang
Recently, it is found that the strong cosmic censorship (SCC) is violated in RNdS black hole by a minimal coupled neutral massless scalar field at the linear perturbation level. Fo…
Black Hole Zeroth Law in Horndeski Gravity
Aofei Sang, Jie Jiang
The four laws of black hole mechanics have been put forward for a long time. However, the zeroth law, which states that the surface gravity of a stationary black hole is a constant…
First Law of Black Hole in the Gravitational Electromagnetic System
Jie Jiang, Aofei Sang, Ming Zhang
After considering the quantum corrections of Einstein-Maxwell theory, the effective theory will contain some higher-curvature terms and nonminimally coupled electromagnetic fields.…
Constraints on High-Order Gravitational Theories from Weak Cosmic Censorship
Jie Jiang, Aofei Sang, Ming Zhang
Weak cosmic censorship conjecture (WCCC) is a basic principle that guarantees the predictability of spacetime and should be valid in any classical theories. One critical scientific…
