DESCRIPTION:Speaker: Dario Feliciangeli\nhosted by Robert Seiringer\nAbstra
 ct: In this talk I shall present recent progress on the Fröhlich Polaron 
 model in the strong coupling regime\, obtained in collaboration with Rober
 t Seiringer. In particular\, I will focus on quantum corrections to the Pe
 kar asymptotics for its ground state energy. Compared to previous works\, 
 the main novelty is that we are able to treat the problem in a translatio
 nal invariant setting\, namely a (sufficiently large) torus in R^3. This
  substantially complicates the discussion and calls for a precise study of
  the set of minimizers of the classical functional(s) corresponding to th
 e Fröhlich Hamiltonian. We carry out this study by introducing an (almos
 t) infinite dimensional diffeomorphism and formalizing some heuristic ar
 guments contained in the physics literature.
