Asymptotic quasinormal modes of a coupled scalar field in the Garfinkle–Horowitz–Strominger dilaton spacetime
Asymptotic quasinormal modes of a coupled scalar field in the Garfinkle–Horowitz–Strominger dilaton spacetime
The analytic forms of the asymptotic quasinormal frequencies of a coupled scalar field in the Garfinkle–Horowitz–Strominger dilaton spacetime are investigated by using the monodromy technique proposed by Motl and Neitzke. It is found that the asymptotic quasinormal frequencies depend not only on the structure parameters of the background spacetime, but …
