Signal of phase transition hidden in quasinormal modes of regular AdS black holes
Yang Guo, Hao Xie, Yan-Gang Miao
We discuss the intrinsic relations between thermodynamic phase transitions and quasinormal modes in regular AdS black holes, specifically in the Bardeen and Hayward AdS classes. To…
Recovery of consistency in thermodynamics of regular black holes in Einstein's gravity coupled with nonlinear electrodynamics
Yang Guo, Hao Xie, Yan-Gang Miao
As one of candidate theories in the construction of regular black holes, Einstein's gravity coupled with nonlinear electrodynamics has been a topic of great concerns. Owing to the…
Regular black holes: A short topic review
Chen Lan, Hao Yang, Yang Guo +1
The essential singularity in Einstein's gravity can be avoidable if the preconditions of Penrose's theorem can be bypassed, i.e., if the strong energy condition is broken in the vi…
Joule-Thomson effect of AdS black holes in conformal gravity
Yang Guo, Hao Xie, Yan-Gang Miao
We investigate the Joule-Thomson effect of AdS black holes in conformal gravity. We derive the Joule-Thomson coefficient in terms of thermodynamic relations and then make an altern…
On heat properties of charged AdS black holes in Gauss-Bonnet gravity coupled with nonlinear electrodynamics
Yang Guo, Yan-Gang Miao
We investigate the heat properties of charged AdS black holes in the Gauss-Bonnet gravity coupled with nonlinear electrodynamics. We consider the thermodynamics of black holes from…
Bounce corrections to gravitational lensing, quasinormal spectral stability and gray-body factors of Reissner-Nordström black holes
Yang Guo, Chen Lan, Yan-Gang Miao
Gravitational lensing in the weak field limit, quasinormal spectra, and gray-body factors are investigated in the Reissner-Nordström spacetime corrected by bounce parameters. Using…
Charged black-bounce spacetimes: Photon rings, shadows and observational appearances
Yang Guo, Yan-Gang Miao
The photon ring, shadow and observational appearance of the emission originating near a charged black-bounce are investigated. Based on the geodesic analysis, we determine the uppe…
Weinhold geometry and thermodynamics of Bardeen AdS black holes
Yang Guo, Yan-Gang Miao
Thermodynamics of Bardeen AdS black holes has attracted a great deal of attentions due to its intrinsic complications and rich phase structures. However, the entropy and thermodyna…
Quasinormal mode and stability of optical black holes in moving dielectrics
Yang Guo, Yan-Gang Miao
We study the quasinormal mode and stability of optical black holes in moving dielectrics. The results show that the real part of complex frequencies is inversely proportional to bu…
