DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IPHT-PHM/7/"
 >Multipoint conformal blocks and Gaudin models</a>\nby Andrea Capelli (INF
 N and Department of Physics\, Florence\, Italy) as part of Séminaire de p
 hysique mathématique IPhT\n\nLecture held in Salle Claude Itzykson\, Bât
 . 774\, Orme des Merisiers.\n\nAbstract\nMassless fermions and anyons on t
 he surface of (3+1)-dimensional topological insulators can be described at
  the semiclassical level by a non-local Abelian gauge theory involving two
  gauge fields.  The theory is non-trivial owing to its solitonic excitatio
 ns with electric and magnetic charges. We compute the partition function a
 nd the solitonic spectrum\, thus showing conformal invariance and electric
 -magnetic self-duality.  This theory also provides a framework for semicla
 ssical bosonization of (2+1)d fermions.\n
