DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/27/">Ov
 erlaps and Fermionic Dualities for Integrable Super Spin Chains</a>\nby Ch
 arlotte Kristjansen (Niels Bohr Institute) as part of London Integrability
  Journal Club\n\n\nAbstract\nThe $\\mathfrak{psu}(2\,2|4)$ integrable supe
 r spin chain underlying the AdS/CFT correspondence has integrable boundary
  states which describe set-ups where $k$ D3-branes get dissolved in a prob
 e D5-brane. Overlaps between Bethe eigenstates and these boundary states e
 ncode the one-point functions of conformal operators and are expressed in 
 terms of the superdeterminant of the Gaudin matrix that in turn depends on
  the Dynkin diagram of the symmetry algebra. The different possible Dynkin
  diagrams of super Lie algebras are related via fermionic dualities and we
  determine how overlap formulae transform under these dualities. As an app
 lication we show how to consistently move between overlap formulae obtaine
 d for $k=1$ from different Dynkin diagrams.\n
