DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IPHT-PHM/11/
 ">Separation of variables and correlation functions</a>\nby Fedor Levkovic
 h-Maslyuk as part of Séminaire de physique mathématique IPhT\n\nLecture 
 held in Salle Claude Itzykson\, Bât. 774\, Orme des Merisiers.\n\nAbstrac
 t\nI will present new results in the separation of variables (SoV) program
  for integrable models. The SoV methods are expected to be very powerful b
 ut until recently have been barely developed beyond the simplest gl(2) exa
 mples. I will describe how to realize the SoV for any gl(N) spin chain and
  demonstrate how to solve the longstanding problem of deriving the scalar 
 product measure in SoV. Using these results I will show how to compute a l
 arge class of correlation functions and overlaps in a compact determinant 
 form. I will also demonstrate the power of SoV in 4d integrable CFT's such
  as the 'fishnet' theory and outline highly promising applications in comp
 utation of exact correlators in N=4 super Yang-Mills theory.\n
