Manipulating lightcone fluctuations in an analogue cosmic string
Jiawei Hu, Hongwei Yu
We study the flight time fluctuations in an anisotropic medium inspired by a cosmic string with an effective fluctuating refractive index caused by fluctuating vacuum electric fiel…
Selected spherical photon orbits around a deformed Kerr black hole
Changqing Liu, Chikun Ding, Jiliang Jing
In this paper, we investigate so-called spherical photon orbits around a deformed Kerr black hole with an extra deformation parameter. The change in the azimuth and the angle…
Gravitational lensing by a black hole with torsion
Lu Zhang, Songbai Chen, Jiliang Jing
In this paper we have investigated the gravitational lensing in a spherically symmetric spacetime with torsion in the generalized Einstein-Cartan-Kibble-Sciama (ECKS) theory of gra…
Repulsive effect for the unbound high energy particles along the rotation axis in the Kerr-Taub-NUT spacetime
Lu Zhang, Songbai Chen, Jiliang Jing
We have investigated the acceleration of the unbound high energy particles moving along the rotation axis in the Kerr-Taub-NUT spacetime, and then study the dependence of the repul…
Dirac perturbations on Schwarzschild-Anti-de Sitter spacetimes: Generic boundary conditions and new quasinormal modes
Mengjie Wang, Carlos Herdeiro, Jiliang Jing
We study Dirac quasinormal modes of Schwarzschild-Anti-de Sitter (Schwarzschild-AdS) black holes, following the generic principle for allowed boundary conditions proposed in \cite{…
Production of gravitational waves during preheating with nonminimal coupling
Chengjie Fu, Puxun Wu, Hongwei Yu
We study the preheating and the in-process production of gravitational waves (GWs) after inflation in which the inflaton is nonminimally coupled to the curvature in a self-interact…
Shadows of Bonnor black dihole by chaotic lensing
Mingzhi Wang, Songbai Chen, Jiliang Jing
We have studied numerically the shadows of Bonnor black dihole through the technique of backward ray-tracing. The presence of magnetic dipole yields non-integrable photon motion, w…
Energy extraction from a Konoplya-Zhidenko rotating non-Kerr black hole
Fen Long, Songbai Chen, Shangyun Wang +1
We have investigated the properties of the ergosphere and the energy extraction by Penrose process in a Konoplya-Zhidenko rotating non-Kerr black hole spacetime. We find that the e…
Shadow casted by a Konoplya-Zhidenko rotating non-Kerr black hole
Mingzhi Wang, Songbai Chen, Jiliang Jing
We have investigated the shadow of a Konoplya-Zhidenko rotating non-Kerr black hole with an extra deformation parameter. The spacetime structure arising from the deformed parameter…
Quasinormal ringing of black holes in Einstein aether theory
Chikun Ding
The gravitational consequence of local Lorentz violation (LV) should show itself in derivation of the characteristic quasinormal ringing of black hole mergers from their general re…
Consistency between dynamical and thermodynamical stabilities for perfect fluid in theories
Xiongjun Fang, Xiaokai He, Jiliang Jing
We investigate the stability criterions for perfect fluid in theories which is an important generalization of general relativity. Firstly, using Wald's general variation pri…
Interaction between two gravitationally polarizable objects induced by thermal bath of gravitons
Puxun Wu, Jiawei Hu, Hongwei Yu
The quadrupole-quadrupole interaction between a pair of gravitationally polarizable objects induced by vacuum fluctuations of the quantum linearized gravitational field is first ob…
Thermodynamical stability for perfect fluid
Xiongjun Fang, Xiaokai He, Jiliang Jing
According to maximum entropy principle, it has been proved that the gravitational field equations could be derived by the extrema of total entropy for perfect fluid, which implies…
Equation of State of Neutron Stars with Junction Conditions in the Starobinsky Model
Wei-Xiang Feng, Chao-Qiang Geng, W. F. Kao +1
We study the Starobinsky or model of for neutron stars with the structure equations represented by the coupled differential equations and the \emph{polytropic}…
Cosmological perturbation and matter power spectrum in bimetric massive gravity
Chao-Qiang Geng, Chung-Chi Lee, Kaituo Zhang
We discuss the linear perturbation equations with the synchronous gauge in a minimal scenario of the bimetric massive gravity theory. We find that the matter density perturbation a…
