Chaos bound for spinning particles in a hairy black hole with two photon spheres
Chuanhong Gao
In this work, we investigate the unstable circular orbits of spinning test particles and the associated classical orbital chaos bound in a hairy black hole spacetime admitting a do…
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…
Quasinormal modes and the correspondence with shadow in black holes with a deficit solid angle and quintessence-like matter
Chengye Yu, Deyou Chen, Chuanhong Gao
In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a -dimensional black hole with a deficit solid angle and quintessence-like matter. We fin…
Angular momentum and chaos bound of charged particles around Einstein-Euler-Heisenberg AdS black holes
Deyou Chen, Chuanhong Gao
In this paper, we investigate influences of the charge and angular momentum of a particle around a charged Einstein-Euler-Heisenberg AdS black hole on a Lyapunov exponent, and find…
Chaos bound and its violation in charged Kiselev black hole
Chuanhong Gao, Deyou Chen, Chengye Yu +1
The chaos bound in the near-horizon regions has been studied through the expansions of the metric functions on the horizon. In this paper, we investigate the chaos bound in the the…
Bound on Lyapunov exponent in Einstein-Maxwell-Dilaton-Axion black holes
Chengye Yu, Deyou Chen, Chuanhong Gao

Quasinormal modes and the correspondence with shadow in a charged black hole in presence of quintessence
Chuanhong Gao, Deyou Chen, Chengye Yu
In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a charged black hole in presence of quintessence. The result shows that the shadow radius de…
The correspondence between shadow and test field in a four-dimensional charged Einstein-Gauss-Bonnet black hole
Deyou Chen, Chuanhong Gao, Xianming Liu +1
In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a four-dimensional charged Einstein-Gauss-Bonnet black hole. The perturbation of a massless…
