Title: An Exterior Field Theory for Hawking Radiation

Abstract: How should one understand the physics of field theories living around a black hole? We know since Einstein that black holes suck in everything that is thrown at them (dissipation into the black hole). But since Hawking, we also know that black holes radiate (Hawking fluctuations of the black hole). Can one set up a field-theoretic description in the exterior of a black hole accounting for both these effects? I will present an affirmative answer to this question (in a simple setup) and try to explain how the black hole modifies the Feynman rules of the field theory outside.
