Entanglement entropy and monotones in scattering process
Jinbo Fan, Gao-Ming Deng, Xi-Jun Ren
In this paper, we study the entanglement property of a 4-particle system. In this system, two initially entangled electrons A and C are scattered by two uncorrelated positrons B an…
The shadows and observational appearance of a noncommutative black hole surrounded by various profiles of accretions
Xiao-Xiong Zeng, Guo-Ping Li, Ke-Jian He
The accretion around the black hole plays a pivotal role in the theoretical analysis of black hole shadow, and of the black hole observation in particular. In this paper, we mainly…
Ultra-spinning Chow's black holes in six-dimensional gauged supergravity and their properties
Di Wu, Shuang-Qing Wu
By taking the ultra-spinning limit as a simple solution-generating trick, a novel class of ultra-spinning charged black hole solutions has been constructed from Chow's rotating cha…
Null hypersurface caustics for high dimensional superentropic black holes
Di Wu, Puxun Wu
A black hole is superentropic if it violates the reverse isoperimetric inequality. Recently, some studies have indicated that some four dimensional superentropic black holes have t…
The feature of shadow images and observed luminosity of the Bardeen black hole surrounded by different accretions
Ke-Jian He, Sen Guo, Shuang-Cheng Tan +1
In this paper, by exploring the photon motion in the region near the Bardeen black hole, the shadow and observation properties of the black hole surrounded by various accretion mod…
Effects of global monopole on critical behaviors and microstructure of charged AdS black holes
Gao-Ming Deng, Jinbo Fan, Xinfei Li
As an intriguing topological defect, global monopole's influence on behaviors of black holes has always been anticipated but still remains less clear. Analyzing the thermodynamics…
