Regular black holes with a nonlinear electrodynamics source

We construct several charged regular black hole metrics employing mass distribution functions which are inspired by continuous probability distributions. Some of these metrics satisfy the weak energy condition and asymptotically behave as the Reissner--Nordstrom black hole. In each case, the source to the Einstein equations corresponds to a nonlinear electrodynamics model, which in the weak field limit becomes the Maxwell theory (compatible with the Maxwell weak field limit or approximation). Furthermore, we include other regular black hole solutions that satisfy the weak energy condition and some of them correspond to the Maxwell theory in the weak field limit.Comment: v1: 19 pages, LaTeX, no figures; v2: typos corrected and one reference removed to match published version in Phys.

“…The ABGB geometry has been studied by a number of authors and from various points of view. See, for example [16,17,18,19,20,21,22,23,24,25,26], where the stability of the ABGB spacetime, its gravitational energy, generalizations and the stress-energy tensor of the quantized field propagating in such a geometry have been analyzed. Especially interesting are the thermodynamic considerations presented in Refs.…”

Regular Black Holes in an Asymptotically De Sitter Universe

A regular solution of the system of coupled equations of the nonlinear electrodynamics and gravity describing static and spherically-symmetric black holes in an asymptotically de Sitter universe is constructed and analyzed. Special emphasis is put on the degenerate configurations (when at least two horizons coincide) and their near horizon geometry. It is explicitly demonstrated that approximating the metric potentials in the region between the horizons by simple functions and making use of a limiting procedure one obtains the solutions constructed from maximally symmetric subspaces with different absolute values of radii. Topologically they are AdS2 × S 2 for the cold black hole, dS2 × S 2 when the event and cosmological horizon coincide, and the Plebański-Hacyan solution for the ultraextremal black hole. A physically interesting solution describing the lukewarm black holes is briefly analyzed.

In this paper, we study quantum corrections to the temperature and entropy of a regular Ayón-Beato-García-Bronnikov black hole solution by using tunneling approach beyond semiclassical approximation. We use the first law of black hole thermodynamics as a differential of entropy with two parameters, mass and charge. It is found that the leading order correction to the entropy is of logarithmic form. In the absence of the charge, i.e., e = 0, these corrections approximate the corresponding corrections for the Schwarzschild black hole.
