Description
In this talk, I will consider the quantum scattering theory of a Yukawa particle field
model in the semi-classical regime. The transition and diffusion amplitudes of such a model will be linked to those of the Schrödinger--Klein--Gordon equation. The phase space properties of asymptotic vacuum states will be highlighted and the concentration around the radiation-free solutions of the SKG equation will be established. I will also discuss the uniqueness of SKG energy minimizers as well as some open questions related to asymptotic completeness. This is a joint work with Marco Falconi and Marco Olivieri.
