Exact Thermodynamics and Two-Horizon Relations of Four Rotating Einstein-Maxwell-Maxwell-Dilaton Embeddings
Hai Huang, Juhua Chen
We establish complete outer-horizon thermodynamics for four exact rotating embeddings of Kerr--Newman and Kaluza--Klein seeds in four-dimensional, asymptotically flat Einstein--Max…
Massless scalar scattering by Kerr-Bertotti-Robinson black holes:transparent-end channels and superradiance
Hai Huang, Xudong Sun, Juhua Chen
We formulate and numerically solve the real-frequency scattering problem for a neutral, minimally coupled, massless scalar on the rotating Kerr--Bertotti--Robinson (Kerr--BR) black…
Thermodynamical phase structures and particle emission rate of charged AdS black hole surrounded by string cloud and quintessence via shadow formalism
Yunxiang Wang, Hongyu Chen, Juhua Chen +1
In this paper, the shadow of the four-dimensional charged AdS black hole surrounded by string cloud and quintessence is derived. The shadow radius shows a strictly monotonic and in…
Scattering and absorption of a charged massive scalar field by a Reissner-Nordström black hole surrounded by perfect fluid dark matter
Hai Huang, Xudong Sun, Juhua Chen
We study the scattering of charged massive particles impinging on a Reissner-Nordström (RN) black hole immersed in perfect fluid dark matter (PFDM). We obtain an approximation of a…
Spinning Particle in Gravitational Field of Black Hole Involving Global Monopole
Qihong Huang, Juhua Chen, Yongjiu Wang
In this paper we study the dynamics of trajectory of a spinning particle in a Schwarzschild spacetime involving a global monopole. We set up the equations of motion and find three…
Geodesic structure of Janis-Newman-Winicour space-time
Sheng Zhou, Ruanjing Zhang, Juhua Chen +1
In the present paper we study the geodesic structure of the Janis-Newman-Winicour(JNW) space-time which contains a strong curvature naked singularity. This metric is an extension o…
Distribution of Entropy of Bardeen Regular Black Hole with Corrected State Density
Hai Huang, Juhua Chen, Yongjiu Wang
We consider corrections to all orders in the Planck length on the quantum state density, and calculate the statistical entropy of the scalar field on the background of the Bardeen…
Geodesic Structure of Test Particle in Bardeen Spacetime
Sheng Zhou, Juhua Chen, Yongjiu Wang
The Bardeen model describes a regular space-time, i.e. a singularity-free black hole space-time. In this paper, by analyzing the behavior of the effective potential for the particl…
Scattering of Scalar Waves by Schwarzschild Black Hole Immersed in Magnetic Field
Juhua Chen, Hao Liao, Yongjiu Wang
The magnetic field is one of the most important constituents of the cosmic space and one of the main sources of the dynamics of interacting matter in the universe. The astronomical…
Quasinormal Modes of Scalar Field in Five-dimensional Lovelock Black Hole Spacetime
Juhua Chen, Yongjiu Wang
In this paper using the third-order WKB approximation, a numerical method devised by Schutz, Will and Iyer, we investigate the quasinormal frequencies of the scalar field in the ba…
Timelike Geodesic Motion in Horava-Lifshitz Spacetime
Juhua Chen, Yongjiu Wang
Recently Hoava proposed a non-relativistic renormalisable theory of gravitation. When restricted to satisfy the condition of detailed balance, this theory is intimately…
Evolution of the interacting viscous dark energy model in Einstein cosmology
Juhua Chen, Yongjiu Wang
In this paper we investigate the evolution of the viscous dark energy (DE) interacting with the dark matter (DM) in the Einstein cosmology model. Using the linearizing theory of th…
