QM Research Seminar: Physics and geometry of the Bethe/Gauge correspondence

Speaker: Mykola Dedushenko (Simons Center for Geometry and Physics, Stony Brook)


Abstract:
I will review my recent work with Nekrasov on the aspects of relation between supersymmetric gauge theories and quantum integrable models. An important role is played by the supersymmetric defects (especially interfaces) in gauge theories, which provide a QFT realization of the infinite-dimensional quantum groups underlying the integrability structures. These defects realize, and in many ways are inspired by, the constructions of Maulik with Okounkov, and Aganagic with Okounkov, of stable envelopes and chamber R-matrices in geometry.
