DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/4/">Bou
 ndary states\, overlaps\, nesting and bootstrapping AdS/dCFT</a>\nby Tamas
  Gombor (Wigner Research Centre for Physics) as part of London Integrabili
 ty Journal Club\n\n\nAbstract\nRecently there have been renewed interest a
 nd relevant progress in calculating overlaps between periodic multiparticl
 e states and integrable boundary states. They appear in quite distinct par
 ts of theoretical physics including  statistical physics and the gauge/str
 ing duality.\nI will give a summary of known overlap formulas and analyze 
 the connection between selection rules and symmetries. I will introduce a 
 nesting procedure for boundary states which provides the factorizing overl
 aps for higher rank algebras automatically. This method can be used for th
 e calculation of the asymptotic all-loop 1-point functions in AdS/dCFT. In
  doing so I will present the solutions of the YBE for the K-matrices with 
 centrally extended su(2|2) symmetry and the generic overlaps of the corres
 ponding boundary states.\nBased on 2004.11329\n
