Holographic Dual of Synge's Identity in AdS/CFT

Bingbing Chen, Deyou Chen

We identify CFT counterparts of Synge's identity for finite AdS geodesics in arbitrary dimensions. Starting from exact finite bulk--boundary pairs, the Synge equation induces endpo…

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

Chuang Yang, Deyou Chen, Bingbing Chen

In this paper, we investigate how the particle spin modulates chaos bound violations in Lorentz-violating black hole spacetimes within the framework of Bumblebee gravity. Using the…

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

Deyou Chen, Chuang Yang, Kangqiao Liu

In this paper, we investigate the chaos bound violation of spinning charged test particles in the Kerr--Newman--AdS spacetime by comparing the Lyapunov exponent of unstable circula…

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…

Lyapunov exponents, phase transition and chaos bound in Kerr-Newman AdS spacetime

Chuang Yang, Chuanhong Gao, Deyou Chen +1

In this paper, we investigate Lyapunov exponents associated with chaotic motions of both massless and massive particles in the vicinity of a Kerr-Newman AdS black hole. Our explora…

Lyapunov exponents as probes for a phase transition of a Kerr-AdS black hole

Deyou Chen, Chuang Yang, Yongtao Liu

In this letter, we study proper time Lyapunov exponents and coordinate time Lyapunov exponents of chaos for both massless and massive particles orbiting a four-dimensional Kerr-AdS…

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…
