CHOU, Yu-Ching  y  HUANG, Weihan. A novel singularity-free black hole with nonlinear magnetic monopole: Hawking radiation and quantum correction. Pap. Phys. [online]. 2022, vol.14, pp.56-62.  Epub 20-Ene-2022. ISSN 1852-4249.  http://dx.doi.org/10.4279/pip.140006.

This paper introduces a nonlinear, magnetically charged, singularity-free black hole model. The Ricci scalar, Kretschmann scalar, horizon, energy conditions, and Hawking radiation corresponding to the singularity-free metric are presented, and the asymptotic behavior and quantum correction of the model are examined. The model was constructed by coupling a mass function with the regular black hole solution under nonlinear electrodynamics in general relativity. Aside from resolving the problem of singularities in Einstein’s theory of general relativity, the model asymptotically meets the quantum correction under an effective field theory. This obviates the need for additional correction terms; in this regard, the model outperforms the black hole models developed by Bardeen and Hayward. Regarding the nonlinear magnetic monopole source of the gravitational field of the black hole, the energy-momentum tensors fulfill weak energy conditions. The model constitutes a novel, spherically symmetric solution to regular black holes.
