Alex Strohmaier (Leibniz University, Hannover)Scattering by metric perturbation and the analytic theory of the stress energy tensor
I will discuss aspects of the implementation of metric perturbations for the fully quantised Klein-Gordon field on a globally hyperbolic spacetime. In particular I will discuss the differentiability of the canonical implementer that can be used to define the quantum stress energy tensor.
