F., México, email: alopezo@esfm.ipn.mx Received 27 May 2014; accepted 26 June 2014 In a D-dimensional Lifshitz black hole we calculate exactly the quasinormal frequencies of a test Dirac field in the massless and zero angular eigenvalue limits.
These results are an extension of the previous calculations in which the quasinormal frequencies of the Dirac field are determined, but in four dimensions.
We discuss the four-dimensional limit of our expressions for the quasinormal frequencies and compare with the previous results.
We also determine whether the Dirac field has unstable modes in the D-dimensional Lifshitz spacetime. Keywords: Quasinormal modes; Dirac field; Lifshitz spacetimes; classical stability. PACS: 04.40.-b; 04.30.Nk; 04.70.Bw; 04.50.Gh 1. Introduction We know condensed matter systems for which the space and time at the critical points (Lifshitz fixed points) show the anisotropic scale invariance ...
