@article{Bodendorfer2019EffectiveQE, title={Effective quantum extended spacetime of polymer Schwarzschild black hole}, author={Norbert Bodendorfer and Fabio M. Mele and Johannes M{\"u}nch}, journal={Classical and Quantum Gravity}, year={2019}, volume={36} }

The physical interpretation and eventual fate of gravitational singularities in a theory surpassing classical general relativity are puzzling questions that have generated a great deal of interest among various quantum gravity approaches. In the context of loop quantum gravity (LQG), one of the major candidates for a non-perturbative background-independent quantisation of general relativity, considerable effort has been devoted to construct effective models in which these questions can be…
