论文摘要
我们提出了改进的Mathematica代码，该代码借助Bernstein Spectral方法来计算一般的黑洞类别，从而允许渐近平坦，DE Sitter或Anti-De Sitter渐近渐近。在搜索纯粹的虚构和不稳定模式时，该方法特别有效，在这里，该方法用于检测带电的标量偏离的渐近脱位型明位dileter dialatonic黑洞的不稳定性区域。我们表明，不稳定性具有超级级别的性质，而Dilaton场基本上影响了不稳定性区域。
We present the improved Mathematica code which computes quasinormal frequencies with the help of the Bernstein spectral method for a general class of black holes, allowing for asymptotically flat, de Sitter or anti-de Sitter asymptotic. The method is especially efficient when searching for purely imaginary and unstable modes and here it is used for detecting the instability region of a charged scalar field in the background of the charged asymptotically de Sitter dilatonic black hole. We show that the instability has superradiant nature and the dilaton field essentially influences the region of instability.
