Observations of Orbiting Hot Spots around Naked Singularities
Yiqian Chen, Peng Wang, Haitang Yang
Recently, it has been reported that photons can traverse naked singularities in the Janis-Newman-Winicour and Born-Infeld spacetimes when these singularities are appropriately regu…
Scalarized Kerr-Newman Black Holes
Guangzhou Guo, Peng Wang, Houwen Wu +1
In this paper, we construct scalarized rotating black holes within the framework of Einstein-Maxwell-scalar models. These models incorporate non-minimal couplings that can induce t…
Holographic deformed entanglement entropy in dS/CFT
Deyou Chen, Xin Jiang, Haitang Yang
In this paper, based on the deformed version of correspondence, we calculate the pseudoentropy for an entangling surface consisting of two ant…
Gravitational Lensing by Born-Infeld Naked Singularities
Yiqian Chen, Peng Wang, Houwen Wu +1
We examine the gravitational lensing phenomenon caused by photon spheres in the Born-Infeld naked singularity spacetime, where gravity is coupled with Born-Infeld electrodynamics.…
Timelike entanglement entropy in dS/CFT
Xin Jiang, Peng Wang, Houwen Wu +1
In the context of dS/CFT, we propose a timelike entanglement entropy defined by the renormalization group flow. This timelike entanglement entropy is calculated in CFT by u…
Superradiance Instabilities of Charged Black Holes in Einstein-Maxwell-scalar Theory
Guangzhou Guo, Peng Wang, Houwen Wu +1
We study time evolutions of charged scalar perturbations on the background of a charged hairy black hole, in which the perturbations can be governed by a double-peak effective pote…
Timelike entanglement entropy and deformation
Xin Jiang, Peng Wang, Houwen Wu +1
In a previous work arXiv:1811.07758 about the deformed CFT, from the consistency requirement of the entanglement entropy theory, we found that in addition to the usu…
Black Holes with Multiple Photon Spheres
Guangzhou Guo, Yuhang Lu, Peng Wang +2
Recently, asymptotically-flat black holes with multiple photon spheres have been discovered and found to produce distinctive observational signatures. In this paper, we focus on wh…
