A Study of Decay Rate of Bound Negative Muons

Jian-Bo Deng, Miao-Yi Deng, Shi-Jie Ma +6

A number of experiments show that the decay lifetimes of muons bound to atomic nuclei are longer than the decay lifetimes of free muons. In this paper, a scheme of extending quantu…

Holographic Timelike Entanglement Entropy from Rindler Method

Peng-Zhang He, Hai-Qing Zhang

For a Lorentzian invariant theory, the entanglement entropy should be a function of the domain of dependence of the subregion under consideration. More precisely, it should be a fu…

Revisit the entanglement entropy with gravitational anomaly

Peng-Zhang He, Hai-Qing Zhang

In this paper we study the entanglement entropy in the CFT, whose gravity dual is AdS spacetime with a Chern-Simons term. Using the generalized Rindler method, we obtain th…

Shadow of topologically charged rotating braneworld black hole

Hao-Ran Zhang, Peng-Zhang He, Lei-Shao +2

In this paper, we discuss optical properties of the topologically charged rotating black hole. We study the horizon, the photon region, the shadow of the black hole and other obser…

Shadow cast by a rotating and nonlinear magnetic-charged black hole in perfect fluid dark matter

Tian-Chi Ma, He-Xu Zhang, Peng-Zhang He +3

We derived an exact solution of the spherically symmetric Hayward black hole surrounded by perfect fluid dark matter (PFDM). By applying the Newman-Janis algorithm, we generalized…

Shadows of rotating Hayward-de Sitter black holes with astrometric observables

Peng-Zhang He, Qi-Qi Fan, Hao-Ran Zhang +1

Motivated by recent work on rotating black hole shadow [Phys. Rev. D101, 084029 (2020)], we investigate the shadow behaviors of rotating Hayward-de Sitter black hole for static obs…

The cosmological constant from space-time discreteness

Qi-Qi Fan, Cong Li, Hao-Ran Zhang +2

We regard the background of space-time as a physical system composed of discrete volume elements at the Planck scale and get the internal energy of space-time by Debye model. A tem…

Bardeen black hole surrounded by perfect fluid dark matter

He-Xu Zhang, Yuan Chen, Tian-Chi Ma +2

We derive an exact solution of the spherically symmetric Bardeen black hole surrounded by perfect fluid dark matter (PFDM). By treating the magnetic charge and dark matter para…

Optical properties of a Brane-World black hole as photons couple to the Weyl tensor

He-Xu Zhang, Cong Li, Peng-Zhang He +2

In this article, we have investigated the equations of motion of the photons coupled to Weyl tensor by the geometric optics approximation and the corresponding shadow in a Brane-Wo…

Joule-Thomson expansion of the Bardeen-AdS black holes

Cong Li, Pengzhang He, Ping Li +1

The Joule-Thomson expansion process is studied for Bardeen-AdS black holes in the extended phase space. Firstly, we get Joule-Thomson coefficient and find that the divergent point…
