Description
In this talk we will discuss the quantization of a charged black hole within the improved dynamics of loop quantum gravity and several properties of its semiclassical effective geometries. Adopting a redefined scalar constraint, that renders the algebra of constraints into a Lie algebra, we apply loop quantum gravity techniques adhered to a novel improved dynamics scheme. The model is solvable in closed form. We explicitly compute effective geometries for small charges, and show that the resulting effective space-times replace the inner horizon with a transition surface that connects trapped and antitrapped regions within the charged black hole interior. Namely, quantum effects stabilize the classical inner horizons in the limit of small charge, where the structure of these space-times remains the same as the uncharged case. We conclude discussing the properties of these effective geometries and show that they do not obey the null energy condition at high curvatures.
