Hawking Radiation of Charged Particles as Tunneling from Kim Black Hole

摘要

In this paper, when considering the conservation of energy, electric charge and angular momentum, we develop the Parikh-Wilczek's quantum tunneling method to study the Hawking radiation of charged particles via tunneling from the event horizon of Kim black hole. The result shows the exact radiation spectrum deviates from the precisely thermal one, but satisfies an underlying unitary theory, which provides a possible solution to the information loss during the black hole evaporation.
