Nonlinear scalarization and thermodynamics in Einstein-Phantom scalar-Gauss-Bonnet theory
Tian-Zhen Dai, Yun Soo Myung, De-Cheng Zou +4
We study nonlinear scalarization of Schwarzschild black-holes for a phantom scalar coupled to the Gauss--Bonnet invariant. Three polynomial couplings satisfying are intr…
Critical Scalarization for a Self-Gravitating Bosonic Condensate
Meng-Yun Lai, Hyat Huang, Wen-Cong Gan +2
We establish a minimal nonrelativistic realization of scalarization in a self-gravitating bosonic condensate coupled to a scalar response field. A local effective-mass shift and no…
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…
Thermodynamics and phase transitions of nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory
De-Cheng Zou, Xu Yang, Meng-Yun Lai +2
We investigate the thermodynamic properties of static nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory with polynomial coupling functions. Based on the sca…
Phase Structure of Scalarized Black Holes in Einstein-Scalar-Gauss-Bonnet Gravity
Carlos Herdeiro, Hyat Huang, Jutta Kunz +3
We revisit scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity and analyze the thermodynamic phase transition between the Schwarzschild solution of general relativity an…
Spontaneous scalarization of regular Hayward black holes in Einstein-nonlinear electromagnetic-scalar gravity
Lan-Lan Cai, Meng-Yun Lai, De-Cheng Zou +2
Regular Hayward black holes provide a useful setting for investigating scalarization in theories with nonminimally coupled matter sectors. Within the framework of Einstein-nonlinea…
Phase transitions of boson stars in scalar-tensor theories
Hyat Huang, Burkhard Kleihaus, Jutta Kunz +3
In scalar-tensor theories, compact objects may experience spontaneous scalarization. Recently, it was shown that matter-induced spontaneous scalarization of neutron stars is predom…
Gravitational lensing effect of black holes in effective quantum gravity
Hao Liu, Meng-Yun Lai, Xiao-Yin Pan +2
In the present work, we investigate the gravitational lensing effects of two quantum-modified black hole models recently proposed in effective quantum gravity. The light deflection…
Identifying doppelgange Black Holes through Shadow Images
Yukun Xu, Hyat Huang, Meng-Yun Lai +1
Recently, an interesting \textit{doppelgänge} black hole solution is obtained in the string-inspired Euler-Heisenberg theory, where the black holes have the same radii but share di…
