In this paper, the tunneling of vector boson particles across the event horizon of Kerr-Newman-de Sitter (KNdS) black hole is investigated using the WKB approximation and Hamilton-Jacobi ansatz to Proca equation. The tunneling probability and radiation spectrum at the event horizon of KNdS black hole is obtained. The modified Hawking radiation of stationary and non-stationary KNdS black hole are also investigated using the Rarita-Schwinger ansatz to the deformed Hamilton-Jacobi method and new tortoise coordinate transformation. It is observed that the modified Hawking temperatures near the event horizon for both stationary and nonstationary space times are dependent on the black hole parameters.

“…The correction to Bekenstein-Hawking entropy for the Schwartzschild black hole and Kerr black hole have been derived by applying Hamilton-Jacobi equation and the first law of black hole thermodynamics [12][13][14]. Many fruitful results have been obtained in [15][16][17] by using Hamilton-Jacobi method. Refs.…”

“…Refs. [32][33][34][35] extended the change in Bekenstein-Hawking entropy by tunneling of fermions across the event horizon of black hole using Dirac equation in curved space time. The general theory of relativity is based on gravity which is impossible to renormalise, therefore many researchers proposed different modified gravity theories.…”

The quantum tunneling radiation of scalar particles near the event horizon of Kerr-de Sitter black hole is investigated in three systems of coordinates namely naive coordinate system, Painleve coordinate system and Eddington coordinate system using Lorentz violation theory in curved space time. The Klein-Gordon equation of scalar particles is transformed into Hamilton-Jacobi equation by using Lorentz violation theory in curved space time. We observe that due to Lorentz violation theory, the expressions of Hawking temperatures, the Bekenstein-Hawking entropies and specific heat capacities near the event horizon of Kerr-de Sitter black hole are modified. The Hawking temperatures, entropies and specific heat capacities increase or decrease depending upon the choices of ether like vectors u α .

“…In this method, appropriate Gamma matrices were chosen and wave functions were inserted into the Dirac equation, the action which is related to Boltzmann factor of emission at Hawking temperature according to semiclassical WKB approximate can be obtained. Using this method, the Hawking radiation in different complicated black holes can be studied [22][23][24][25]. Kruglov [26,27] proposed the thermal radiation from a black hole by using Hamilton-Jacobi ansatz to Proca equation, WKB approximation and Feynman prescription.…”

In this paper, the modified Hawking temperature of a static Riemann space-time is studied using the generalized Klein-Gordon equation and the generalized Dirac equation. Applying the Kerner-Mann quantum tunneling method, the modified Hawking temperatures for scalar particles and fermions that cross the event horizon of the black hole have been derived. We observe that the quantum gravity effects reduce the rise of thermal radiation temperature of the black hole.
