Hawking radiation as quantum tunneling from a noncommutative Schwarzschild black hole. (English) Zbl 1149.83324

Summary: We study the tunneling process through the quantum horizon of a Schwarzschild black hole in noncommutative space-time. This is done by considering the effect of smearing of the particle mass as a Gaussian profile in flat space-time. We show that even in this noncommutative setup there will be no correlation between the different modes of radiation, which reflects the fact that information does not come out continuously during the evaporation process at least at late time. However, due to space-time noncommutativity, information might be preserved by a stable black hole remnant.
