要旨

The existence of a minimal length, predicted by different theories of quantum
gravity, can be phenomenologically described in terms of a generalized
uncertainty principle. We consider the impact of this quantum gravity motivated
effect onto the information budget of a black hole and the sparsity of Hawking
radiation during the black hole evaporation process. We show that the
information is not transmitted at the same rate during the final stages of the
evaporation and that the Hawking radiation is not sparse anymore when the black
hole approaches the Planck mass.
