Black hole scalarizations induced by parity violations
Hao-Jie Lin, Tao Zhu, Shao-Jun Zhang +1
It is well-known that parity symmetry is broken in the weak interaction but conserved for Einstein's general relativity and Maxwell's electromagnetic theory. Nevertheless, parity s…
Nonlinear instability and scalar clouds of spherical exotic compact objects in scalar-Gauss-Bonnet theory
Shao-Jun Zhang
In this work, we present a new type of scalar clouds supported by spherically symmetric horizonless compact objects in the scalar-Gauss-Bonnet theory. Unlike the previous spontaneo…
Tachyonic Instability of Reissner-Nordström-Melvin Black Holes in Einstein-Maxwell-Scalar Theory
Hengyu Xu, Shao-Jun Zhang
In the framework of Einstein-Maxwell-scalar theory, we studied scalar field perturbations of Reissner-Nordström-Melvin (RNM) black holes, which describes the RN black holes immerse…
An implementation of the matrix method using Chebyshev grid
Shui-Fa Shen, Wei-Liang Qian, Hong Guo +2
In this work, we explore the properties of the matrix method for black hole quasinormal modes on the nonuniform grid. In particular, the method is implemented to be adapted to the…
Gravito-Electromagnetic Perturbations and QNMs of Regular Black Holes
Kun Meng, Shao-Jun Zhang
In the framework of Einstein's gravity coupled to nonlinear electromagnetic fields, we study gravito-electromagnetic perturbations of magnetic regular black holes. The master equat…
Magnetic-induced Spontaneous Scalarization in Dynamcial Chern-Simons Gravity
Shao-Jun Zhang, Bin Wang, Eleftherios Papantonopoulos +1
In the framework of the dynamical Chern-Simons gravity, we study the scalar field perturbations of the Reissner-Nordström-Melvin spacetime, which describes a charged black hole per…
