Dirac Fermions around Schwarzschild black holes with quintessence

Abstract

The present paper deals with the Schwarzschild black holes with quintessence whose geometry is sourced by a magnetic monopole in the context of non-linear electrodynamics. After briefly discussing the timelike geodesics and radial motion, a special attention is given to the Dirac equation. In the massless case, the radial function is expressed in terms of Heun general functions. The outgoing wave solutions are used to compute the Hawking temperatures on the horizons and the corresponding heat capacities.
