No New Quantum Thermal Effect of Dirac Particles in a Charged Vaidya - de Sitter Black Hole
S. Q. Wu, X. Cai
Abstract
It is shown that Hawking radiation of Dirac particles does not exist for P1, Q2 components but for P2, Q1 components in a charged Vaidya - de Sitter black hole. Both the location and the temperature of the event horizon change with time. The thermal radiation spectrum of Dirac particles is the same as that of Klein-Gordon particles. Our result demonstrates that there is no new quantum effect in the thermal radiation of Dirac particles in any spherically symmetry black holes.
