Kerr--Newman--Kasuya Black Hole Tunnelling Radiation

The radiation of black hole contributes to the shrinking of the event horizon such that the background space-time should not be fixed. In this study we take into account the self-gravitation effect to study the radiation of Kerr--Newman--Kasuya black hole as tunnelling. Using the facts of energy conservation and angular momentum conservation we derive the tunnelling rate and show that the spectrum of the radiation as tunnelling is not purely thermal.
