本文研究四维Schwarzschild de-Sitter黑洞中带壁的大泛音准正规模式,发现其领头阶与$n$成正比且与反弹时间成反比,并分析了$n^{-1}$阶修正项。
AI 中文摘要
我们研究了在静态球面处放置壁的四维Schwarzschild de-Sitter黑洞中,大泛音有质量标量场的准正规模式。在壁处施加Dirichlet边界条件。在领头阶,大泛音的准正规模式在$n\gg 1$时按$n$标度,并与反弹时间成反比。我们分析了渐近展开中直至$n^{-1}$阶的修正项。
英文摘要
We study large-overtone quasi-normal modes of a massive scalar field in a four-dimensional Schwarzschild de-Sitter black hole in the presence of a wall placed at the static sphere. Dirichlet boundary condition is imposed at the wall. At leading order the quasi-normal modes with large overtones scale as $n$ for $n\gg 1$ and are inversely proportional to the bouncing time. We analyze correction terms up to $n^{-1}$ order in the asymptotic expansion.
