Hawking radiation As tunneling [PDF]

open access: yesPhysical Review Letters, 1999
We present a short and direct derivation of Hawking radiation as a tunneling process, based on particles in a dynamical geometry. The imaginary part of the action for the classically forbidden process is related to the Boltzmann factor for emission at ...
