Quantum transitions of minimum energy for Hawking quanta in highly
  excited black holes: problems for loop quantum gravity?
  By analysing some recent results by Yoon, which arise from loop quantum
gravity and from the assumption of the locality of photon emission in a black
hole, we argue that they are not consistent with our recent semi-classical
results for highly excited black holes. Maybe that the results by Yoon can be
correct for non-highly excited black holes, but, in any case, our analysis
renders further problematical the match between loop quantum gravity and
semi-classical theory.
