| contents | This study investigates the evaporation process of a Schwarzschild black hole, incorporating quantum corrections arising from conformal anomaly and vacuum polarization. We demonstrate that these corrections significantly alter the Hawking radiation and the black hole's thermodynamic behavior. Specifically, the black hole exhibits a maximum temperature, after which the radiation begins to decrease, eventually leading to the cessation of Hawking radiation. The final state of the black hole at the end of the evaporation process is found to be an extremal remnant with a vanishing Hawking temperature. Furthermore, we show that the black hole entropy is modified, acquiring a logarithmic correction. Hawking radiation is also examined through the lens of the tunneling method, providing a consistent picture of these quantum effects. |
