Spin-mediated modulation of chaos bound violation in Lorentz-violating black hole spacetimes

Chuang Yang, Deyou Chen, Bingbing Chen

We investigate how the particle spin modulates chaos bound violations in Lorentz-violating black hole spacetimes within the framework of Bumblebee gravity. Using the Mathisson-Papa…

Chaos bound for spinning particles in Kerr-Newman-AdS black holes

Deyou Chen, Chuang Yang, Kangqiao Liu

In this paper, we employ spinning test particles as probes to investigate the regulatory effects of particle and black hole parameters on the violation of the chaos bound in Kerr-N…

Unveiling Inner Shadows and Polarization Signatures of Rotating Einstein-Gauss-Bonnet Black Holes

Bing-Bing Chen, Chen-Yu Yang, Deyou Chen +1

Based on the backward ray-tracing method, this paper numerically investigates the shadow and polarization images of rotating Einstein-Gauss-Bonnet (EGB) black hole within the frame…

Motions of spinning particles and chaos bound in Reissner-Nordström spacetime

Chuang Yang, Deyou Chen, Yongtao Liu

Previous research showed that the chaos bound proposed in \cite{MSS} can be violated under specific conditions within the scalar fields surrounding black holes. In this paper, we e…

Interplay of Lyapunov exponents, phase transitions and chaos bound in nonlinear electrodynamics black hole

Chuanhong Gao, Chuang Yang, Tetvui Chong +1

In this paper, we investigate Lyapunov exponents of chaos for both massless and charged particles around a non-linear electrodynamics black hole, and explore their relationships wi…

Gravitational Lensing by Transparent Janis-Newman-Winicour Naked Singularities

Deyou Chen, Yiqian Chen, Peng Wang +2

The Janis-Newman-Winicour (JNW) spacetime can describe a naked singularity with a photon sphere that smoothly transforms into a Schwarzschild black hole. Our analysis reveals that…
