چکیده :
The tunnelling mechanism is widely used to explain Hawking radiation.
However, in many cases the analysis used to obtain the
Hawking temperature only involves comparing the emission probability
for an outgoing particle with the Boltzmann factor. Banerjee
and Majhi improved this approach by explicitly finding a black
body spectrum associated with black holes. Their result, obtained
using a reformulation of the tunnelling mechanism, is in contrast
to that of Parikh and Wilczek, who found an emission probability
that is compatible with a non-strictly thermal spectrum. Using the
recently identified effective state for a black hole, we solve this contradiction
via a slight modification of the analysis by Banerjee and
Majhi. The final result is a non-strictly black body spectrum from
the tunnelling mechanism. We also show that for an effective temperature,
we can express the corresponding effective metric using
Hawking’s periodicity arguments. Potential important implications
for the black hole information puzzle are discussed.
