The quasinormal modes of Kerr-Newman black hole
The study on the quasinormal modes of field around black holes will be helpful to testify the existence and reveal the nature of black holes. In this paper, we take the Kerr-Newman black holes as study object and electromagnetic field as an initial perturbation field. After presenting some object pictures from numerical simulation, we analyze and discuss the different effects caused by different parameters of black holes.
This proceeding is based on arXiv:1609.09299 [hep-th], where we use 4-point amplitudes in order to normalize the vertex operators for massless and massive strings living at D-brane intersections and next to evaluate Yukawa couplings between these states. Using our results we are planning to proceed and evaluate physical processes which might be visible at LHC.
