Scalarization of Einstein-Euler-Heisenberg black hole with multiple horizons
Hong Guo, Yun Soo Myung
Scalarizations of the Einstein-Euler-Heisenberg (EEH) black hole (EEHBH) with multiple horizons are investigated in the EEH-scalar theory by introducing a quadratic scalar coupling…
Polar perturbations of dilaton-Euler-Heisenberg black holes
Sheng-Yuan Li, Yun Soo Myung, Ming Zhang +2
We investigate the quasinormal modes of polar metric-dilaton perturbations around the dilaton-Euler-Heisenberg (dEH) black holes with dilaton hair. The dEH black holes are obtained…
Gauss-Bonnet scalarization of charged qOS-black holes
Hong Guo, Wontae Kim, Yun Soo Myung
The Gauss-Bonnet (GB) scalarization for charged quantum Oppenheimer-Snyder (cqOS)-black holes is investigated in the Einstein-Gauss-Bonnet-scalar theory with the nonlinear electrod…
Anisotropic matter and nonlinear electromagnetics black holes
Yun Soo Myung, Wonwoo Lee
It is shown that anisotropic matter black holes with two parameters and correspond to nonlinear electrodynamics (NED) black holes with power-index and charge term $ξ(s…
Charge-dependent scalarization of Einstein- Euler-Heisenberg black holes
Lina Zhang, Yun Soo Myung, De-Cheng Zou +1
Charge-dependent scalarization of the Einstein-Euler-Heisenberg (EEH) black hole is carried out in the EEH-scalar theory by introducing an exponential scalar coupling with cou…
Spin-Induced Nonlinear Scalarization of Kerr Black Holes in Einstein-scalar-Gauss-Bonnet Gravity
Meng-Yun Lai, Hyat Huang, Jutta Kunz +2
We investigate spin-induced scalarization of Kerr black holes in an Einstein-scalar-Gauss-Bonnet (EsGB) model that does not admit a linear tachyonic instability of the scalar-free…
