Abstract

In this work, we investigate the tunneling phenomenon of a charged Dirac particle emerging from a thermal horizon of a hot NUT-Kerr-Newman-Kasuya-Anti-de Sitter (HNKNK-AdS) black hole. Considering the tunneling formalism, we report the Hawking temperature of the charged Dirac particle through the horizon and the heat capacity of the HNKNK-AdS black hole. It is found that the effective Hawking temperature for the black hole depends on the black hole's parameters, such as electric and magnetic charges, magnetic mass, the cosmological constant, and the angular momentum of the black hole. The Hawking radiation for the Kerr-Newman black hole is reduced. It is shown that there is a small correction to the Hawking thermal spectrum. The heat capacity for the HNKNK-AdS black hole is found different from the previous work, and for the Kerr-Newman black hole is also reduced.
