Abstract
By using the deformed dispersion relation, we study the modified fermions tunneling for rotating charged black hole in de Sitter spacetime. Firstly, the Rarita-Schwinger equation is modified in the gravitational background, and then the deformed Hamilton-Jacobi equation is derived by a semi-classical approximation method. It is shown that the form of the correctional Hamilton-Jacobi equation does not depend on the spin of the fermions field in the semi-classical approximation, and its correctional term is given by − 2 σ m g t t ( ω − e A t ) 2 . Using the correction, we also investigate the fermion tunneling radiation for Kerr-Newman-de Sitter black hole spacetime, and the results show that the correctional temperature and entropy depend on the angular parameters of the horizon of the rotating black hole background.
