“…The motion of a scalar particle obeys the Klein-Gordon equation, namely, (P μ P μ + m 2 ) = 0. When quantum gravity effects were considered, the modified Klein-Gordon equation was derived in [29]. Here, we take into account the electromagnetic field and quantum gravity effects.…”

Taking into account quantum gravity effects, we investigate the tunnelling radiation of charged fermions in the Kerr-Newman black hole. The result shows that the corrected Hawking temperature is determined not only by the parameters of the black hole, but also by the energy, angular momentum and mass of the emitted fermion. Meanwhile, an interesting found is that the temperature is affected by the angle θ . The quantum gravity correction slows down the evaporation.

This paper is devoted to study charged fermion particles tunneling through the horizon of Kerr-Newman-AdS black hole surrounded by quintessence by using Hamilton-Jacobi ansatz. In our analysis, we investigate Hawking temperature as well as quantum corrected Hawking temperature on account of generalized uncertainty principle. Moreover, we discuss the effects of correction parameter β on the corrected Hawking temperature T e−H , graphically. We conclude that the temperature T e−H vanishes when β = 100, whereas for β < 100 and β > 100, the temperature turns out to be positive and negative, respectively. We observe that the graphs of T e−H w.r.t. quintessence parameter α exhibit behavior only for the particular ranges, i.e., 0 < α < 1/6, charge 0 < Q ≤ 1 and rotation parameter 0 < a ≤ 1. For smaller and larger values of negative Λ, as horizon increases, the temperature decreases and increases, respectively.

This paper discusses the effects of the mass and the angular momentum of massive vector and scalar particles on the Hawking temperature manifested under the effects of the generalized uncertainty principle (GUP). In particular, we calculate the Hawking temperature of a black hole in a warped DGP gravity model in the framework of the quantum tunneling method. We use the modified Proca and Klein-Gordon equations previously determined from the GUP Lagrangian in the spacetime background of a warped Dvali-Gabadadze-Porrati (DGP) metric, with the help of Hamilton-Jacobi (HJ) and semiclassical (WKB) approximation methods. We find that as a special case of a warped DGP black hole solution, the Hawking temperature of a Schwarzschild-de Sitter (SdS) black hole can be determined. Furthermore, the Hawking temperature is influenced by the mass and the angular momentum of vector and scalar particles and depends on which of those types of particles is being emitted by the black hole. We conclude that the nonthermal nature of the Hawking spectrum leads to Planck-scale nonthermal correlations, shedding light on the information paradox in black hole evaporation.
