Decay of a charged scalar field around a black hole: Quasinormal modes of RN, RNAdS, and dilaton black holes

It is well known that the charged scalar perturbations of the Reissner-Nordstr\"om metric will decay slower at very late times than the neutral ones, thereby dominating in the late time signal. We show that, at the stage of quasinormal (QN) ringing, on the contrary, the neutral perturbations will de... View More
