Phase diagrams of quasinormal frequencies for Schwarzschild, Kerr, and Taub-NUT black holes
Chen Lan, Meng-Hu Li, Yan-Gang Miao
The Newman-Janis algorithm, which involves complex-coordinate transformations, establishes connections between static and spherically symmetric black holes and rotating and/or axia…
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…
A regular black hole as the final state of evolution of a singular black hole
Han-Wen Hu, Chen Lan, Yan-Gang Miao
We propose a novel black hole model in which singular and regular black holes are combined as a whole and more precisely singular and regular black holes are regarded as different…
Regular black holes with improved energy conditions and their analogues in fluids
Chen Lan, Yan-Gang Miao, Yi-Xiong Zang
On the premise of the importance of energy conditions for regular black holes, we propose a method to remedy those models that break the dominant energy condition, e.g., the Bardee…
Singularities of regular black holes and the monodromy method for asymptotic quasinormal modes
Chen Lan, Yi-Fan Wang
We use the monodromy method to investigate the asymptotic quasinormal modes of regular black holes based on the explicit Stokes portraits. We find that, for regular black holes wit…
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…
Acoustic regular black hole in fluid and its similarity and diversity to a conformally related black hole
Chen Lan, Yan-Gang Miao, Yi-Xiong Zang
We address an interesting question in the present paper that whether the acoustic gravity can be applied as a tool to the study of regular black holes. For this purpose, we constru…
Semi-classical predictions of cosmological wave-packets from ridge-lines
Chen Lan, Yi-Fan Wang
We introduce a concept of ridge-lines to investigate the semi-classical prediction from wave-packets with arbitrary width in conventional quantum mechanics and the Wheeler--DeWitt…
Entropy and Topology of Regular Black Holes
Chen Lan, Yan-Gang Miao
We calculate the entropy of spherically symmetric regular black holes by the path integral and Noether-charge method. Both methods provide an evidence that the entropy of regular b…
Gliner Vacuum, Self-consistent Theory of Ruppeiner Geometry for Regular Black Holes
Chen Lan, Yan-Gang Miao
In the view of the Gliner vacuum, we remove the deformations in the first law of mechanics for regular black holes, where one part of deformations associated with black hole mass w…
Quasinormal Modes and Thermodynamics of Regular Black Holes
Chen Lan, Yan-Gang Miao, Hao Yang
By applying the dimensionless scheme, we investigate the quasinormal modes and phase transitions analytically for three types of regular black holes. The universal deviations to th…
Dynamically Assisted Schwinger Effect at Strong Coupling with Its Holographic Extension
Chen Lan, Yi-Fan Wang, Huifang Geng +1
At strong-coupling and weak-field limit, the scalar Schwinger effect is studied by the field-theoretical method of worldline instantons for dynamic fields of single-pulse and sinus…
Integrable Minisuperspace Models with Liouville Field: Energy Density Self-Adjointness and Semiclassical Wave Packets
Alexander A. Andrianov, Chen Lan, Oleg O. Novikov +1
The homogeneous cosmological models with a Liouville scalar field are investigated in classical and quantum context of Wheeler-DeWitt geometrodynamics. In the quantum case of quint…
