Chaos bound violation by spinning particles in Gauss-Bonnet-AdS black holes

Xiaowei Li, Mengxuan Wu, Guoping Li

The paper examines how spinning test particles in Gauss‑Bonnet anti‑de Sitter black holes can violate the chaos bound, showing that the Lyapunov exponent depends on particle spin,…

Particle decay and energy conservation in the Kerr-Newman black hole

Bing-Bing Chen, Guo-Ping Li, Ke Wang +1

The paper investigates how a particle decays in Kerr‑Newman black hole spacetime, showing that the mass loss of the parent particle is converted into kinetic energy and analyzing h…

Horizon-scale intensity and polarization images of rotating Konoplya-Zhidenko black holes with thick accretion flows

Bing-Bing Chen, Chen-Yu Yang, Guo-Ping Li +1

We investigate the shadow and polarization images of a Konoplya-Zhidenko rotating non-Kerr black hole surrounded by a geometrically thick and optically thin accretion flow. The acc…

Gravitational lensing and observational features of a dynamic black hole

Ke-Jian He, Guo-Ping Li, Li-Fang Li +1

In this work, we investigate the gravitational lensing effects and the dynamic evolution of the shadow of Vaidya black holes by employing backward ray-tracing techniques. Within th…

Testing the chaos bound in the spinor field of Einstein-Euler-Heisenberg-Anti-de Sitter spacetime

Xiaowei Li, Bingbing Chen, Guoping Li

Violations of the chaos bound have been observed in scalar fields. In this work, we investigate the Lyapunov exponents of chaotic particles in the spinor field of an Einstein-Euler…

Probing Observable Features of Lorentz violation in Low-Energy Hořava Gravity with Accretion Disk Images of Black Hole

Meng-Die Zhao, Yu-Yan Wang, Ke-Jian He +1

In this paper, we study the observable signatures of Lorentz violation (LV) in low-energy Horava gravity by simulating the images and polarization features of rotating LV black hol…
