Generic degeneracy and entropy in loop quantum gravity
Abstract
Without imposing the trapping boundary conditions and only from within the very definition of area it is shown that the loop quantization of area manifests an unexpected degeneracy in area eigenvalues. This could lead to a deeper understanding of the microscopic description of a quantum black hole. If a certain number of semiclassically expected properties of black holes are imposed on a quantum surface its entropy coincides with the BekensteinHawking entropy.
