DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/32/">In
 tegrable E-models\, 4d Chern-Simons theory and affine Gaudin models</a>\nb
 y Benoit Vicedo as part of London Integrability Journal Club\n\n\nAbstract
 \nTwo-dimensional integrable field theories are characterised by the exist
 ence of infinitely many integrals of motion. Recently\, two unifying frame
 works for describing such theories have emerged\, based on four-dimensiona
 l Chern-Simons theory in the presence of surface defects and on Gaudin mod
 els associated with affine Kac-Moody algebras. I will explain how these fo
 rmalisms can be used to construct infinite families of two-dimensional int
 egrable field theories. The latter can all naturally be formulated as so-c
 alled E-models\, a framework for describing Poisson-Lie T-duality in sigma
 -models. The talk will be based on the joint work [arXiv:2008.01829] with 
 M. Benini and A. Schenkel and [2011.13809] with S. Lacroix.\n
