Quasinormal modes of D3-brane black holes

Abstract

We investigate a method to evaluate quasinormal modes of D3-brane black holes by wave interpretation of fields on a D3-brane based on Feynman's spacetime approach. We perturbatively solve the wave equation which describes propagation of a dilaton wave in a bulk space and its interaction with the D3-brane. The condition obtained for the quasinormal modes is qualitatively equivalent to that evaluated in the usual scattering of the dilaton in the black three-brane spacetime in the corresponding supergravity description.
