    Scalar Particles Tunneling Radiation in the Demianski-Newman Spacetime with Influences of Quantum Gravity by Zhonghua Li

    Published 2020-01-01
    “…We get the effective temperature with influences of quantum gravity and compare this temperature with the original temperature of the Demianski-Newman black hole. We find that it is similar to the case of fermions; for scalar particles, the influence of quantum gravity will also slow down the increase of Hawking temperatures, which naturally leads to remnants left in the evaporation.…”
