Quasinormal modes for Weyl neutrino field in RN black holes

We employ the WKB approximation up to the third order to determine the low-lying quasinormal modes for the Wey1 neutrino field in RN black holes, which are the most relevant to the evolution of the field around a black hole in the intermediate stage. It is shown that the quasinormal mode frequencies for the Wey1 neutrino field in RN black holes are different from those in Schwarzschild black holes owing to the charge-induced additional gravitation, and the variations of the quasinormal mode frequencies for the Weyl neutrino field are similar to those for integral spin fields in RN black holes.Astronomy & AstrophysicsPhysics, MultidisciplinaryPhysics, Particles & FieldsSCI(E)8ARTICLE4917-9252
