The result shows that the tunneling rates at the event horizon and the cosmic horizon are related to Bekenstein-Hawking entropy if we take the energy conservation into consideration, and the true radiate spectrum is not precisely thermal.展开更多

We consider the case that the dynamical coupling constant λ= 1, when it reduces to Einstein's General Relativity at large scales and the black hole behaves like the Reissner-Nordstr6m black hole. The result shows that though the black hole entropy bears logarithmic correction, the tunneling probability is still related to its differences for the scalar particles and Dirac particles.展开更多
