Abstract
In this paper, we study the quantum tunneling of scalar particles near the event horizon of Kerr–Newman black hole under Lorentz violation theory. First, the modified Hamilton–Jacobi equation under Lorentz violation theory in the curved spacetime is reviewed. The modified Hawking temperatures, heat capacities and entropies of Kerr–Newman black hole in frame dragging coordinates and Eddington coordinate are derived. The modified Hawking temperature, heat capacity and change in Bekenstein–Hawking entropy of Kerr–Newman black hole are found to be modified due to Lorentz violation theory and they depend not only on Lorentz violation parameter [Formula: see text] but also on ether-like vector [Formula: see text].
