These systems are often refered\nto as "nonrelativistic QED" or "Paul i--Fierz Hamiltonians"\, and for\ntheir analysis the renormalization group based on the Feshbach-Schur\nmap proved to be a powerful tool whose isosp ectrality property\nyields very precise information.\n\nThe talk starts wi th a review of the model described above and of\n(some of) the results tha t have been obtained. The main focus lies\,\nhowever\, on the renormalizat ion group based on the Feshbach--Schur\nmap and the progress that has been made in the past three decades\,\nincluding the smooth Feshbach--Schur ma p and the continuous RG flow.\nEventually\, recent results obtained in col laboration with\nM. Ballesteros\, J. Geisler\, and S. Karimi are presented .\n LOCATION:https://researchseminars.org/talk/IAMP_seminars/196/ END:VEVENT END:VCALENDAR
