Subtleties in the quasi-classical calculation of Hawking radiation
arXiv:0805.2653 · doi:10.1142/S0218271808013947
Abstract
he quasi-classical method of deriving Hawking radiation is investigated. In order to recover the original Hawking temperature one must take into account a previously ignored contribution coming from the temporal part of the action. This contribution plus a contribution coming from the spatial part of the action gives the correct temperature.
