Quantum Tunneling of Dirac Particles from the Generalized Spherical Symmetric Evaporating Charged Black Hole

摘要

Kerner and Mann’s recent research shows that, for an uncharged and non-rotating black hole, its Hawking temperature and tunneling rate can be exactly obtained by the fermion tunneling method from its event horizon. In this paper, considering the tunneling charged particles with spin 1/2, we extend Kerner and Mann’s method to the generalized spherical symmetric evaporating charged black hole which is non-stationary. In order to investigate the fermion tunneling through the event horizon, we choose a set of appropriate matrices γ μ . As a result, the tunneling probability and truly effective temperature are well recovered by charged fermions tunneling from the black hole.
