Charged Dirac perturbations on Reissner-Nordström black holes in a cavity: quasinormal modes with Robin boundary conditions
Jia Liu, Mengjie Wang, Zishuo Wang +3
We investigate charged Dirac quasinormal spectra on Reissner-Nordström black holes in a mirror-like cavity. For this purpose, we first derive charged Dirac equations, and \textit{…

Gravitational lensing effect of black holes in effective quantum gravity
Hao Liu, Meng-Yun Lai, Xiao-Yin Pan +2
In the present work, we investigate the gravitational lensing effects of two quantum-modified black hole models recently proposed in effective quantum gravity. The light deflection…
