DISCUSSION ON THE CHARACTERISTICS OF THE QUANTUM TUNNELING RADIATION OF GLOBAL MONOPOLE CHARGED BLACK HOLE

Considering energy conservation, adopting KKW method, the tunneling effect of global monopole charged black hole was deeply studied. The result shows that the emission of particle on the event horizon relates to the change of Bekenstein–Hawking entropy and the spectrum is not pure thermal. Moreover, the corrections to the entropy and temperature of the black hole are presented.

Correction to Hawking radiation of the stationary axisymmetric NUT-Taub black hole

Adopting a new method of quantum radiation as tunnelling, and taking energy conservation into account, the tunnelling radiation characteristics of the stationary axial symmetric NUT-Taub black hole are studied. The result shows that the tunnelling rate of particles at the event horizon of the black hole is relevant to Bekenstein–Hawking entropy and the real spectrum is not precisely thermal at all.
