Query: Flux-area operator and black hole entropy   We show that, for space-times with inner boundaries, there exists a natural
area operator different from the standard one used in loop quantum gravity.
This new flux-area operator has equidistant eigenvalues. We discuss the
consequences of substituting the standard area operator in the
Ashtekar-Baez-Corichi-Krasnov definition of black hole entropy by the new one.
Our choice simplifies the definition of the entropy and allows us to consider
only those areas that coincide with the one defined by the value of the level
of the Chern-Simons theory describing the horizon degrees of freedom. We give a
prescription to count the number of relevant horizon states by using spin
components and obtain exact expressions for the black hole entropy. Finally we
derive its asymptotic behavior, discuss several issues related to the
compatibility of our results with the Bekenstein-Hawking area law and the
relation with Schwarzschild quasi-normal modes.
