Infraparticle scattering and renormalization in non-relativistic QED — •Thomas Chen — Department of Mathematics, Princeton University, Fine Hall, Washington Road, Princeton, NJ 08544, USA

We discuss some recent work related to the infrared problem in non-relativistic Quantum Electrodynamics (QED). In particular, we explain the link between rigorous infrared mass renormalization, the identification of coherent infrared representations, and the construction of infraparticle scattering states without infrared cutoffs. This is in part based on joint works with V. Bach, J. Fröhlich, A. Pizzo, and I.M. Sigal.
