Entropy Quantization of Reissner-Nordstrom Black Hole

The Hawking temperature and Entropy of Reissner-Nordstrom (RN) black hole can be derived from energy quantization of the test particle moving around different circular orbits which is analog to the Bohr's atomic model. Energy transitions (recall the Rydberg formula) can lead to radiations that can be experimentally detected in the future. Following gravitoelectromagnetism (GEM) it is possible to split the upper bound of energy without the quantization effects on energy level splitting in atoms and molecules due to the hypothetical nature of the gravitipole. Here we have mentioned the entropy and other thermodynamic properties of RN black holes within string theory going well beyond the thermodynamic limit.
