Revisiting thermodynamic topologies of black holes
Chaoxi Fang, Jie Jiang, Ming Zhang
In the generalized off-shell free energy landscape, black holes can be treated as thermodynamic topological defects. The local topological properties of the spacetime can be reflec…
White dwarf binary modulation can help stochastic gravitational wave background search
Shijie Lin, Bin Hu, Xue-Hao Zhang +1
For the stochastic gravitational wave backgrounds (SGWBs) search centred at the milli-Hz band, the galactic foreground produced by white dwarf binaries (WDBs) within the Milky Way…
Parameter estimation of eccentric gravitational waves with a decihertz observatory and its cosmological implications
Tao Yang, Rong-Gen Cai, Zhoujian Cao +1
Eccentricity of compact binaries can improve the parameter estimation of gravitational waves (GWs). In this paper, we first investigate the parameter estimation of eccentric GWs wi…
Finite-distance gravitational deflection of massive particles by a rotating black hole in loop quantum gravity
Yang Huang, Zhoujian Cao
A rotating black hole in loop quantum gravity was constructed by Brahma, Chen, and Yeom based on a nonrotating counterpart using the revised Newman-Janis algorithm recently. For su…
Extending Gibbons-Werner method to bound orbits of massive particles
Yang Huang, Bing Sun, Zhoujian Cao
The Gibbons-Werner method for the gravitational deflection angle of unbound particles in static spherically symmetric spacetimes is based on Jacobi metric and Gauss-Bonnet theorem.…

The system of gravity coupled to the non-rotational dust field is studied at both classical and quantum levels. The scalar constraint of the system can be written in the form of a…
The linearized second law for any higher curvature gravity with the scalar and the electromagnetic fields
Xin-Yang Wang, Jie Jiang
The first law of black hole thermodynamics is suitable for any diffeomorphism invariant gravity, and the entropy in the first law is the Wald entropy which is highly dependent on t…

Tsai-Chen Lee, Zezhou Hu, Minyong Guo +1
In this work, we study circular motions of charged particles and their polarized images around the Kerr black hole immersed in a weak magnetic field. We pay special attention to th…
Splitting the Echoes of Black Holes in Einstein-nonlinear Electrodynamic Theories
Aofei Sang, Ming Zhang, Shao-Wen Wei +1
Black hole echo is an important observable that can help us better understand gravitational theories. We present that the non-linear electrodynamic black holes can admit the multi-…
