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…
Superradiant instability of a massive scalar on the Kerr spacetime
Yun Soo Myung
We investigate the superradiant instability of Kerr black holes under a massive scalar perturbation. We obtain a potential when expanding the scalar potential for…
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…
Superradiant instability of dyonic Reissner-Nordstrom black holes
Yun Soo Myung
We investigate the superradiant instability of dyonic Reissner-Nordström (dRN) black holes with two charges under a charged massive scalar perturbation. Two conditions for possessi…
Superradiant instability in slowly rotating Kerr-Newman black holes
Yun Soo Myung
We study the superradiant instability of slowly rotating Kerr-Newman (sKN) black holes under a charged massive scalar perturbation. These black holes resemble closer the Reissner-N…
Revisiting superradiant stability of Kerr-Newman black holes under a charged massive scalar
Yun Soo Myung
We revisit the superradiant stability of Kerr-Newman black holes under a charged massive scalar perturbation. We obtain a newly suitable potential which is not singular at the oute…
