Abstract
We study real-time correlators in the Kerr/CFT correspondence. The near-horizon geometry of extreme and near-extremal Kerr black holes could be taken as the warped AdS spacetimes with the warping factor being a function of angular variable θ We show that for the perturbations whose equations of motions could be decomposed into the angular part and radial part, their real-time correlation functions could be computed from warped AdS/CFT correspondence. We find that the retarded Green's functions, the cross sections and the quasi-normal modes are all in perfect match with the dual CFT predictions. The same analysis is also generalized to the charged Newman-Kerr black holes. © SISSA 2010.
