The ring-shaped shadow of a rotating naked singularity with a complete photon sphere
《Chinese Physics C》2024年第10期284-294,共11页Mingzhi Wang Guanghai Guo Pengfei Yan Songbai Chen Jiliang Jing 
Supported by the National Natural Science Foundation of China(12105151);the Natural Science Foundation of Shandong Province,China(ZR2020QA080);partially Supported by the National Natural Science Foundation of China(11875026,11875025,12035005)。
We investigate the shadows of the Konoplya-Zhidenko naked singularity.In the spacetime of the Konoplya-Zhidenko naked singularity,not only an unstable retrograde light ring(LR)but also an unstable prograde LR exists,l...

Observational signatures of rotating black holes in the semiclassical gravity with trace anomaly
《Chinese Physics C》2024年第8期257-265,共9页Zhenyu Zhang Yehui Hou Minyong Guo 
Supported by the National Natural Science Foundation of China(12275004,12205013,11873044);"the Fundamental Research Funds for the Central Universities"(2021NTST13)。
In a recent work by Fernandes[Phys.Rev.D 108(6),L061502(2023)],an exact stationary and axisymmetric solution was discovered in semiclassical gravity with type-A trace anomaly.This was identified as a quantum-corrected...

Preliminary analyses of the dynamics and thermodynamics of rotating regular black holes
《Chinese Physics C》2024年第7期191-210,共20页杨昊 余长江 缪炎刚 
Supported in part by the National Natural Science Foundation of China(12175108)。
We investigate the dynamic and thermodynamic laws governing rotating regular black holes.By analyzing dynamic properties,i.e.,the interaction between scalar particles and rotating regular black holes,we establish the ...

Erratum:Corrigendum to"Effect of dark energy models on the energy content of charged and rotating black holes"[Chinese Phys.C,46(2022)015101]
《Chinese Physics C》2023年第12期195-196,共2页Asia Liaqat Ibrar Hussain 
In Liaqat and Hussain(2022)it was proved that the effect of dark energy with w_(n)=1/3 causes a reduction in the energy content of the quintessential charged-Kerr spacetime.This result needs correction as it is observ...

Superradiance of massive scalar particles around rotating regular black holes
《Chinese Physics C》2023年第7期151-172,共22页杨昊 缪炎刚 
Supported in part by the National Natural Science Foundation of China(11675081,12175108)
Regular black holes,as part of an important attempt to eliminate the singularities in general relativity,have been of wide concern.Because the superradiance associated with rotating regular black holes plays an indisp...

Effect of nonlinear electrodynamics on shadows of slowly rotating black holes
《Chinese Physics C》2023年第2期260-269,共10页汤九阳 刘云旗 钱卫良 岳瑞宏 
Supported by the National Key R&D Program of China(2020YFC2201400)。
In this study,we investigate the effect of nonlinear electrodynamics on the shadows of charged,slowly rotating black holes with the presence of a cosmological constant.Rather than the null geodesic of the background b...

Entropic destruction of heavy quarkonium in a rotating hot and dense medium from holography
《Chinese Physics C》2022年第11期100-105,共6页Ping-ping Wu Zi-qiang Zhang Xiangrong Zhu 
Supported by the NSFC(11805052,12147219)。
Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force,which would induce the dissociation of heavy quarkonium.In this study,we inv...

Holographic Schwinger effect in a rotating strongly coupled medium
《Chinese Physics C》2022年第10期178-183,共6页Yi-Ze Cai Rui-Ping Jing Zi-Qiang Zhang 
We perform a potential analysis on the holographic Schwinger effect in a rotating deformed AdS blackhole background.We calculate the total potential of a quark-antiquark(QQ)pair in an external electric field and evalu...
