Detecting Lorentz-violation induced by a tensor field with S-star's motion around Sgr A*
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a unique probe of extensions to standard model. The orbiting motions of the S-stars around the supermassive black h…
Coarse Graining Holographic Black Holes in Higher Curvature Gravity
Qiongyu Qi
We consider the holographic description of the dynamical black hole entropy in higher curvature gravity which proposed by Hollands-Wald-Zhang. On the bulk side, we show that…
Probing a Lorentz-violating parameter from orbital precession of the S2 star around the galactic centre supermassive black hole
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a promising probe of extensions to general relativity. The supermassive black hole Sgr~A* and the orbit of the S-st…
Entanglement Entropy and Thermodynamics of Dynamical Black Holes
Weizhen Jia, Qiongyu Qi, Christina Gao
We explore the thermodynamic and entanglement properties of dynamical black holes based on the recently proposed dynamical black hole entropy by Hollands-Wald-Zhang. We first provi…
Timelike bound orbits and pericenter precession around black hole with conformally coupled scalar hair
Qi Qi, Xiao-Mei Kuang, Yong-Zhuang Li +1
We investigate the geodesic motions of timelike particles around a static hairy black hole with conformally coupled scalar field. We mainly focus on the effects of the scalar charg…
