DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/64/">Ho
 mogeneous Yang-Baxter deformations as undeformed yet twisted models</a>\nb
 y Riccardo Borsato (Santiago de Compostela U.\, IGFAE) as part of London I
 ntegrability Journal Club\n\n\nAbstract\nI will review recent progress in 
 the study of a class of integrable deformations of sigma models known as "
 homogeneous Yang-Baxter". These deformations can be understood as generali
 sations of the well known TsT transformations. In fact\, rather than defor
 mations\, the homogeneous Yang-Baxter procedure too can be reinterpreted a
 s imposing twisted worldsheet boundary conditions in the undeformed sigma 
 model. I will explain how to construct the twist in the generic case\, whi
 ch generalises the twist of TsT from abelian to non-abelian. I will also u
 se the expression for the twist to discuss the construction of the classic
 al spectral curve in some examples. To conclude\, I will mention some open
  questions related to the quantum integrability of these models.\n
