Stability of Reissner-Nordström black hole in de Sitter background under charged scalar perturbation

Zhiying Zhu, Shao-Jun Zhang, C. E. Pellicer +2

We find a new instability in the four-dimensional Reissner-Nordstrom-de Sitter black holes against charged scalar perturbations with vanishing angular momentum, $l=0$. We show that…
