Band structure of the black hole entropy spectrum in loop quantum gravity

Iván Agulló, J. Fernando Barbero G., Enrique F. Borja, Jacobo Díaz-Polo, Eduardo J.S. Villaseñor

I will present different techniques for the study of the detailed band structure in the degeneracy spectrum that gives rise to the black hole entropy discretization in LQG. Particularly, I will motivate the introduction of a new variable in the black hole degeneracy generating function starting from a qualitative understanding of the spectrum structure, and show how this new variable allows to isolate the different bands and study their properties analytically.
