Abstract


A way to search for a signal of space-time noncommutativity is to study a quasinormal mode spectrum of the Reissner-Nordström black hole in the presence of noncommutativity. In this paper, we chose a particular NC deformation defined by the angular twist. We investigate a noncommutative (NC) deformation of a complex scalar field, minimally coupled with a classical (commutative) near extremal Reissner-Nordström background. The theory is manifestly invariant under the deformed  gauge symmetry group. Using the EOM for the NC complex scalar field in RN background, the QNM spectrum is calculated for a particular range of parameters coresponding to the near extremal limit.
