An implementation of the matrix method using Chebyshev grid
Shui-Fa Shen, Wei-Liang Qian, Hong Guo +2
In this work, we explore the properties of the matrix method for black hole quasinormal modes on the nonuniform grid. In particular, the method is implemented to be adapted to the…

Matrix method for perturbed black hole metric with discontinuity
Shui-Fa Shen, Wei-Liang Qian, Kai Lin +2
Recent studies based on the notion of black hole pseudospectrum indicated substantial instability of the fundamental and high-overtone quasinormal modes. Besides its theoretical no…
