Phase transitions in four-dimensional AdS black holes with a nonlinear electrodynamics source
Ramon Becar, P. A. Gonzalez, Joel Saavedra +2
In this work we consider black hole solutions to Einstein theory coupled to a nonlinear power-law electromagnetic field with a fixed exponent value. We study the extended phase spa…
Horizon curvature and spacetime structure influences on black hole scalarization
Hong Guo, Xiao-Mei Kuang, Eleftherios Papantonopoulos +1
Black hole spontaneous scalarization has been attracting more and more attention as it circumvents the well-known no-hair theorems. In this work, we study the scalarization in Eins…
Accuracy of estimation of parameters with space-borne gravitational wave observatory
Chao Zhang, Yungui Gong, Bin Wang +1
Employing the Fisher information matrix analysis, we estimate parameter errors of TianQin and LISA for monochromatic gravitational waves. With the long-wavelength approximation we…
Thermodynamics of 2+1 dimensional Coulomb-Like Black Holes from Non Linear Electrodynamics with a traceless energy momentum tensor
Mauricio Cataldo, P. A. González, Joel Saavedra +2
In this work we study thermodynamics of 2+1-dimensional static black holes with a nonlinear electric field. Besides employing the standard thermodynamic approach, we investigate th…
Object picture of scalar field perturbation on Kerr black hole in scalar-Einstein-Gauss-Bonnet theory
Shao-Jun Zhang, Bin Wang, Anzhong Wang +1
Scalar perturbations around the Kerr black hole in scalar-Einstein-Gauss-Bonnet (sEGB) theory are studied in the time domain. To overcome the "outer boundary problem" that usually…
Asymptotical quasinormal mode spectrum for piecewise approximate effective potential
Wei-Liang Qian, Kai Lin, Cai-Ying Shao +2
It was pointed out that the black hole quasinormal modes resulting from a piecewise approximate potential are drastically distinct from those pertaining to the original black hole…
Curvature Scalarization of Black Holes in f(R) Gravity
Zi-Yu Tang, Bin Wang, Thanasis Karakasis +1
We consider f(R) gravity theories in the presence of a scalar field minimally coupled to gravity with a self-interacting potential. When the scalar field backreacts to the metric w…
Primordial black holes and secondary gravitational waves from the Higgs field
Zhu Yi, Yungui Gong, Bin Wang +1
We devise a novel mechanism and for the first time demonstrate that the Higgs model in particle physics can drive the inflation to satisfy the cosmic microwave background observati…
Echoes from phantom wormholes
Hang Liu, Peng Liu, Yunqi Liu +2
We study the time evolution of the test scalar and electromagnetic fields perturbations in configurations of phantom wormholes surrounded by dark energy with state parameter $ω< -1…
Acoustic black hole in Schwarzschild spacetime: quasi-normal modes, analogous Hawking radiation and shadows
Hong Guo, Hang Liu, Xiao-Mei Kuang +1
Various properties of acoustic black holes constructed in Minkowski spacetime have been widely studied in the past decades. Recently the acoustic black holes in general spacetime w…
On quasinormal frequencies of black hole perturbations with an external source
Wei-Liang Qian, Kai Lin, Jian-Pin Wu +2
In the study of perturbations around black hole configurations, whether an external source can influence the perturbation behavior is an interesting topic to investigate. When the…
Black Hole Scalarization in Gauss-Bonnet Extended Starobinsky Gravity
Hai-Shan Liu, H. Lu, Zi-Yu Tang +1
We propose a class of higher-derivative gravities that can be viewed as the Gauss-Bonnet extension of the Starobinsky model. The theory admits the Minkowski spacetime vacuum whose…
Thermodynamics of Shearing Massless Scalar Field Spacetimes is Inconsistent With the Weyl Curvature Hypothesis
Daniele Gregoris, Yen Chin Ong, Bin Wang
Our Universe has an arrow of time. In accordance with the second law of thermodynamics, entropy has been increasing ever since the Big Bang. The fact that matter is in thermal equi…
No static regular black holes in Einstein-complex-scalar-Gauss-Bonnet gravity
Kai Lin, Shaojun Zhang, Chao Zhang +3
In this brief report, we investigate the existence of 4-dimensional static spherically symmetric black holes (BHs) in the Einstein-complex-scalar-Gauss-Bonnet (EcsGB) gravity with…
Full analytical formulas for frequency response of space-based gravitational wave detectors
Chunyu Zhang, Qing Gao, Yungui Gong +3
The discovery of gravitational waves, which are ripples of space-time itself, opened a new window to test general relativity, because it predicts that there are only plus and cross…
Exploring non-singular black holes in gravitational perturbations
Hang Liu, Chao Zhang, Yungui Gong +2
We calculate gravitational perturbation quasinormal modes (QNMs) of non-singular Bardeen black holes (BHs) and singularity-free BHs in conformal gravity and examine their spectra i…
