"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," researchers in Waterloo, Canada report.
"This could lead to a deeper understanding of the microscopic description of a quantum black hole," wrote M.H. Ansari and colleagues.

The researchers concluded: "If a certain number of semi-classically expected properties of black holes are imposed on a quantum surface its entropy coincides with the Bekenstein-Hawking entropy."

Ansari and colleagues published their study in NPB...

Does this approach need the Immirzi parameter?
