Abstract

In the zero momentum limit we exactly calculate the quasinormal frequencies of the massive Dirac field propagating in a Lifshitz black brane. Our results are an extension of those for the massive Klein–Gordon field in the zero momentum limit, but in contrast to the boson field for which only the Dirichlet boundary condition was imposed at the asymptotic region, here we impose two different boundary conditions far from the event horizon and compare the values obtained for the quasinormal frequencies. Furthermore, based on our results we determine some relevant limits, study the classical stability of the quasinormal modes of the Dirac field and determine its relaxation times.
