Photon Motion and Shadows of Rotating Black Holes with Nonlinear Electromagnetic and Anisotropic Matter Fields
Mou Xu, Jianbo Lu, Yu Liu +1
This paper investigates the effects of the nonlinear electromagnetic field and the anisotropic matter field on photon motion, shadow structures, and the energy emission rate of a r…
Multiqubit coherence of mixed states near event horizon
Wen-Mei Li, Jianbo Lu, Shu-Min Wu
We investigate the coherence of mixed Greenberger-Horne-Zeilinger (GHZ) and W states for bosonic and fermionic fields when a subset of () qubits experiences Hawking radiat…
Does fermionic entanglement always outperform bosonic entanglement in dilaton black hole?
Wen-Mei Li, Jianbo Lu, Shu-Min Wu
It has traditionally been believed that fermionic entanglement generally outperforms bosonic entanglement in relativistic frameworks, and that bosonic entanglement experiences sudd…
Entropic uncertainty and coherence in Einstein-Gauss-Bonnet gravity
Wen-Mei Li, Jianbo Lu, Shu-Min Wu
We investigate tripartite quantum-memory-assisted entropic uncertain and quantum coherence for GHZ and W states of a fermionic field in the background of a spherically symmetric bl…
Nonseparability of multipartite systems in dilaton black hole
Shu-Min Wu, Xiao-Wei Teng, Wen-Mei Li +2
We investigate the nonseparability of N-partite quantum systems by employing the Abe-Rajagopal (AR) -conditional entropy for both free bosonic and fermionic fields in the backgr…
Particle dynamics and optical appearance of charged spherically symmetric black holes in bumblebee gravity
Mou Xu, Jianbo Lu, Ruonan Li +2
In this paper, we study the particle dynamics, shadow, and optical appearance of charged black holes (BHs) in bumblebee gravity. Firstly, we find that the Lorentz-violation paramet…
