Chaotic particle dynamics near a traversable wormhole throat
Xin Zhao, Xing-Kun Zhang, Ya-Peng Hu +1
This study investigates the nonlinear dynamics of a test particle near the traversable wormhole throat under an external harmonic potential. One-dimensional radial perturbation ana…
Kiselev black hole and the ultra-slow evaporating behavior
Chen-Hao Wu, Xiao Liang, Ya-Peng Hu
Kiselev solution is a metric that describes black holes immersed in a quintessence-like dark energy background. By introducing a dynamic state parameter , the Kiselev solution…
Constraints on non-canonical chaotic inflation from ACT DR6 and BICEP/Keck data
Wei Yang, Chen-Hao Wu, Ya-Peng Hu
In this study, we precisely evaluated the feasibility of the chaotic inflation model within a non-canonical kinetic framework. By applying the slow-roll approximation and imposing…
Cosmological coupled black holes immersed in dark sector
Chen-Hao Wu, Yue Chu, Ya-Peng Hu
Motivated by theoretical and observational developments of cosmological coupled black holes, we construct an exact analytical solution for a black hole immersed in an anisotropic d…
Imprints of Topological Thermodynamics on Black Hole Dynamics
Yue Chu, Chen-Hao Wu, Ya-Peng Hu
By employing Duan's topological method, we classify critical points by their topological charge Q = +/-1 or 0. Previous work (Wei et al., Phys. Rev. D 105, 104003, 2022) investigat…
Curled orbit and epicyclic oscillation of charged particles around the weakly magnetized black hole in the presence of Lorentz violation
Hai-Yang Zhang, Ya-Peng Hu, Yu-Sen An
In this paper, we investigate the motion of charged particles around the weakly magnetized Schwarzschild-like bumblebee black hole which has Lorentz symmetry breaking. Charged part…
