Asymptotic expansion of cavity Quasi-Normal Modes in Schwarzschild de-Sitter black hole
Abstract
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≫ 1 and are inversely proportional to the bouncing time. We analyze correction terms up to n−1 order in the asymptotic expansion.
