Please note the special day, time and location. 听The study of graviton Hawking radiation, renormalized interactions of听dynamical gravitons with other matter fields, and quantum back reaction听of Hawking radiation on the black hole horizon all require the knowledge听of the graviton propagator on a black hole spacetime. I will discuss an听explicit mode-decomposed construction of the de Donder gauge graviton听propagator for the Unruh state on the eternal Schwarzschild spacetime. 听De Donder gauge is chosen for its covariance and locality properties.听This is joint work with F. Bussola (Pavia).
