Quasinormal frequencies of the Dirac field in the massless topological black hole

A. López-Ortega

Abstract


Motivated by the recent computations of the quasinormal frequencies of higher dimensional black holes, we exactly calculate the quasinormal frequencies of the Dirac field, propagating in $D$-dimensional ($D \geq 4$) massless topological black hole. From the exact values of the quasinormal frequencies for the fermion and boson fields we discuss whether the recently proposed bound on the relaxation time of a perturbed thermodynamical system is satisfied in the $D$-dimensional massless topological black hole. Also we study the consequences of these results.
