Abstract

In the framework of loop quantum cosmology, particularly within the quantum Oppenheimer-Snyder model, the semiclassical Ashtekar-Pawlowski-Singh (APS) metric is associated with a static, spherically symmetric black hole that incorporates quantum effects derived from the APS metric. This quantum-corrected black hole can be interpreted as a modified Schwarzschild black hole, where the Schwarzschild metric function is adjusted by an additional term proportional to M2r4\frac{M^{2}}{r^{4}}, with rr denoting the radial coordinate and M,M, the black hole mass. In this study, we show that such a quantum-mechanically modified black hole can arise in the context of nonlinear electrodynamics with either electric or magnetic charge. This charged, quantum-corrected solution is then matched to a dust ball of constant mass MAPSM_{APS}, governed by the APS metric, at a timelike thin-shell possessing nonzero mass mm and electric charge QQ or magnetic charge PP. Analytically, it is demonstrated that the thin-shell oscillates around an equilibrium radius r=Reqr=R_{eq}, which is expressed in terms of % M_{APS}, mm, and QQ or PP.
