We investigate the massive particle's tunneling radiation from Schwarzchild black holes in higher-dimensional de Sitter and Anti-de Sitter space-times. Difference from the mass-less particle, the geodesics of the massive particle is not light-like, but decided by the phase velocity. We focus on s-waves, extend Parikh and Wilczek's semi-classical tunneling method, and calculate the massive particle's emission rate. It is shown that the emission rate is relevant to the change of the black hole's entropy respectively, and the result takes the same functional form as that of the mass-less particle.

In this paper, by using the modified Dirac equation based on the generalized uncertainty principle, close to the Planck scale, we investigate the quantum tunneling and remnant of a quantum-modified Schwarzschild space–time. We successfully calculate corrected tunneling rate, Hawking temperature, and minimum nonzero mass. The results also show that the correction of quantum gravity, which effectively inhibits the growth of temperature of quantum-modified Schwarzschild space–time, can prevent the black hole from evaporating completely, predicting the existence of the remnant of a black hole.

The aim of this paper is to investigate Hawking radiation of Dirac particles from the Dilaton space-time with squashed horizons by improving the method of Kerner and Man's tunneling analysis. We construct appropriate matrices for general covariant Dirac equation, and derive the tunneling probability and Hawking temperature. The results show that both Dirac particles and scalar particles radiate at the same Hawking temperature.
