Gravitational Lensing by Transparent Janis-Newman-Winicour Naked Singularities
Deyou Chen, Yiqian Chen, Peng Wang +2
The Janis-Newman-Winicour (JNW) spacetime can describe a naked singularity with a photon sphere that smoothly transforms into a Schwarzschild black hole. Our analysis reveals that…
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…
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.…
Appearance of an Infalling Star in Black Holes with Multiple Photon Spheres
Yiqian Chen, Guangzhou Guo, Peng Wang +2
Photon spheres play a pivotal role in the imaging of luminous objects near black holes. In this paper, we examine observational appearances of a star freely falling in hairy black…
Connections between reflected entropies and hyperbolic string vertices
Peng Wang, Houwen Wu, Haitang Yang
In this paper, we establish connections between reflected entropies of multipartite mixed states in CFT and hyperbolic string vertices of closed string field theory (CSFT). W…
Non-commutativity from the double sigma model
Dimitri Polyakov, Peng Wang, Houwen Wu +1
We show how non-commutativity arises from commutativity in the double sigma model. We demonstrate that this model is intrinsically non-commutative by calculating the propagators. I…
