We study the quasinormal mode of the perturbation of the scalar field interacting with the electromagnetic field in the backgrounds of Schwarzschild AdS black hole, the Reissner-Nordstrom AdS black hole and the Born-Infeld AdS black hole. We disclose influence by the electric charge Q, the coupling between the scalar and electromagnetic field q and the Born-Infeld parameter b on the quasinormal frequencies of the scalar perturbation. We observe the possible growing mode in the perturbation when the scalar field strongly couples to the electromagnetic field. When the electromagnetic field becomes nonlinear described by the Born-Infeld electrodynamics, the nonlinearity described by the Born-Infeld parameter can hinder the growing mode to appear in the scalar perturbation. The quasinormal mode of the scalar field perturbation can help us further understand the physics in the holographic superconductor.

“…The study of QNM has been an intriguing subject of discussions for the last few decades [1,2,3]. Despite its potential astrophysical interest which could lead to the direct identification of the black hole existence through gravitational wave observation to be realized in the near future [1,2], the QNM has also been argued as a testing ground for fundamental physics.…”

“…It was argued that the QNMs of AdS black holes have direct interpretation in term of the dual conformal field theory(CFT) [3,4,5,6,7,8,9,13]. Attempts of using QNMs to investigate the dS/CFT correspondence has also been given [10].…”

We have studied the quasinormal modes and the late-time tail behaviors of scalar, electromagnetic and gravitational perturbations in the Schwarzschild black hole pierced by a cosmic string. Although the metric is locally identical to that of the Schwarzschild black hole so that the presence of the string will not imprint in the motion of test particles, we found that quasinormal modes and the late-time tails can reflect physical signatures of the cosmic string. Compared with the scalar and electromagnetic fields, the gravitational perturbation decays slower, which could be more interesting to disclose the string effect in this background.

“…Motivated by the discovery of the AdS/CFT correspondence, the investigation of QNM in anti-de Sitter(AdS) spacetimes became appealing in the past several years. It was argued that the QNMs of AdS black holes have direct interpretation in term of the dual conformal field theory(CFT) [3,4,5,6,7,8,9]. Attempts of using QNMs to investigate the dS/CFT correspondence have also been given [10].…”

We reexamined the argument that the quasinormal modes could be a probe of the phase transition of a topological black hole to a hairy configuration by investigating general scalar perturbations. We found further evidence in the quasinormal modes for this phase transition. For the general black hole configurations, we observed that although the quasinormal modes can present us different phases of different configurations, it is not powerful to disclose the phase transition at the critical point.
