Quasinormal modes of coupled metric-dilaton perturbations in two-dimensional stringy black holes
Wen-Hao Bian, Zhu-Fang Cui
We investigate the quasinormal modes (QNMs) associated with intrinsic metric-dilaton coupled perturbations of the Mandal-Sengupta-Wadia (MSW) black hole in two-dimensional string t…

Massive scalar field perturbations in noncommutative-geometry-inspired Schwarzschild black hole
Wen-Hao Bian, Zhu-Fang Cui
In this paper, based on noncommutative-geometry-inspired Schwarzschild black hole, we employ a third-order WKB approximation approach to systematically calculate the quasinormal mo…
