Quantum corrections to Dymnikova-Schwinger black holes in Einstein-Gauss-Bonnet gravity

Abstract: This work investigates black holes within a modified framework of gravity that incorporates quantum-inspired corrections and a fundamental minimal length scale. By integrating Einstein-Gauss-Bonnet gravity with a specially tailored matter source that models quantum particle creation, we derive novel, non-singular black hole solutions. These black holes exhibit rich horizon structures and, notably, do not undergo complete evaporation -- instead, they stabilize into permanent remnants. In addition to analyzing the thermodynamic implications of quantum corrections to Dymnikova-Schwinger black holes, we examine their quasinormal mode spectra using the WKB approximation, alongside their associated energy emission rates. Our findings provide compelling new perspectives on how quantum effects may address foundational issues such as the black hole information loss paradox.
