Multi-scale methods in atomic physics

Zusammenfassung: The purpose of this lecture is to report on recent progress in understanding atomic physics when the electrons are coupled to the quantized radiation field. First, it will be shown that a groundstate persists, then I will present a simple argument, based on a multi-scale virial theorem, showing that excited bound states of an atom turn into resonances. Some comments on Rayleigh scattering will conclude my lecture.
Alle Interessierten sind hiermit herzlich eingeladen.
