Abstract
In this paper, using Hamilton-Jacobi ansatz, we investigate scalar particle tunneling radiation in the Demianski-Newman spacetime. 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.

Hawking proposed that there exists radiation in black holes
When effects of quantum gravity are taken into account, we investigated fermions’ tunneling from the charged and rotating black strings [44]
We found that quantum gravity corrections slow down the increases of the temperatures, which naturally leads to remnants left in the evaporation
Summary
Hawking proposed that there exists radiation in black holes. The study of the black hole radiation is one of the important directions of black hole physics. We found that for black string, the uncharged and unrotating case, the correction of Hawking temperature is only affected by the mass of emitted fermions and the quantum gravitational corrections slow down the increases of the temperature, which naturally leads to remnants left in the evaporation, too. We do not discuss fermions but focus on scalar particle tunneling radiation in the DemianskiNewman spacetime with influences of quantum gravity. Using the Hamilton-Jacobi ansatz, we investigate scalar particle tunneling radiation in the Demianski-Newman spacetime. We find that it is similar to the case of fermions; for scalar particles, the quantum gravity effects slow down the increase of Hawking temperatures.
