Analytical approximations to charged black hole solutions in Einstein-Maxwell-Weyl gravity
Sheng-Yuan Li, Ming Zhang, De-Cheng Zou +1
The Homotopy Analysis Method (HAM) is a useful method to derive analytical approximate solutions of black holes in modified gravity theories. In this paper, we study the Einstein-W…
Nonlinearly scalarized rotating black holes in Einstein-scalar-Gauss-Bonnet theory
Meng-Yun Lai, De-Cheng Zou, Rui-Hong Yue +1
In this paper, we discuss a fully nonlinear mechanism for the formation of scalarized rotating black holes in Einstein-scalar-Gauss-Bonnet gravity, where Kerr black holes are linea…
Analytical approximate solutions for scalarized AdS black holes
De-Cheng Zou, Bo Meng, Ming Zhang +3
The spontaneous scalarization of Schwarzscild-AdS is investigated in the Einstein-scalar-Gauss--Bonnet (ESGB) theory. Firstly, we construct scalarized AdS black holes numerically.…
Thermodynamic and tachyonic instability for asymptotically flat black holes
Yun Soo Myung, De-Cheng Zou, Meng-Yun Lai
It was confirmed that the negative modes of the Euclidean section for asymptotically flat black holes reveal the thermodynamic instability of these black holes in the grand canonic…
Spin-Charge induced spontaneous scalarization of Kerr-Newman black holes
Meng-Yun Lai, Yun Soo Myung, Rui-Hong Yue +1
We investigate the tachyonic instability of Kerr-Newman (KN) black holes in the Einstein-Maxwell-scalar (EMS) theory with a positive coupling parameter . This corresponds to exp…
Spin-induced scalarization of Kerr-Newman black holes in Einstein-Maxwell-scalar theory
Meng-Yun Lai, Yun Soo Myung, Rui-Hong Yue +1
In this paper, we consider the tachyonic instability of Kerr-Newman (KN) black holes in the Einstein-Maxwell-scalar (EMS) theory with nonminimal negative scalar coupling to Maxwell…
Echoes from Asymmetric Wormholes and Black Bounce
Min-Yan Ou, Meng-Yun Lai, Hyat Huang
The time evolution of the field perturbations in the wormhole and black bounce backgrounds are investigated. We find that the asymmetry of spacetime results in the asymmetry of the…
