Bifurcation and spectral instability of asymptotic quasinormal modes in the modified Pöschl-Teller effective potential
GR Li, WL Qian, RG Daghigh - Physical Review D, 2024 - APS
The Pöchl-Teller effective potential mimics an asymptotically de Sitter black hole bounded
by an event horizon and a cosmological one. Owing to the benefit of being analytically …

Universality of instability in the fundamental quasinormal modes of black holes
We elaborate on a criterion for the emergence of instability in the fundamental mode recently
