| contents | In this work we present a supersymmetric extension of the Reissner-Nordström spacetime in the framework of quantum cosmology. We achieve this by supersymmetrizing the Wheeler-DeWitt equation for a Kantowski-Sachs cosmological model defined in the interior region between the event and Cauchy horizons. We carry out this analysis following the Dirac and the reduced phase space quantization approaches and compare them. In the quantum regime we describe the novelties introduced by supersymmetry and highlight the differences with the pure bosonic case. At the classical level we analyse some limits that lead to metrics which are different than the usual Reissner-Nordström form. We show that in some regions of the spacetime, true singularities arise. In addition, we study the geodesics equation of a massive particle moving in the region where supersymmetry contributions are dominant. |
