Abstract
We consider an atom interacting with the quantized electromagnetic field in the standard model of non-relativistic QED. The nucleus is supposed to be fixed. We prove smoothness of the resolvent and local decay of the photon dynamics for quantum states in a spectral interval I just above the ground state energy. Our results are uniform with respect to I. Their proofs are based on abstract Mourreʼs theory, a Mourre inequality established by Fröhlich, Griesemer and Sigal (see Fröhlich et al. (2008) [14]), Hardy-type estimates in Fock space, and a low-energy dyadic decomposition.
