Black-hole entropy in loop quantum gravity

Krzysztof A Meissner

Show affiliations


We calculate the black-hole entropy in loop quantum gravity as a function of the horizon area and provide the exact formula for the leading and sub-leading terms. By comparison with the Bekenstein–Hawking formula, we uniquely fix the value of the 'quantum of area' in the theory.
