Quantum tunneling of fermions from Grumiller black hole

Abstract

In this paper, we examine the Hawking radiation of the Grumiller black hole via the quantum tunneling of fermions.To this end, we consider the Dirac equation in that black hole geometry.It is shown that the surface temperatures of the event horizon in either coordinate systems [singular and non-singular (Painleve-Gullstrand)] correspond to the standard Hawking temperature of the Grumiller black hole.
