ABSTRACT: Bethe/gauge correspondence relates quantum integrable systems to supersymmetric gauge theories. One of the mathematical consequences of this relation is the identification of the quantum cohomology ring of certain varieties with Bethe subalgebras of quantum algebras. In this talk the two dimensional gauge theories corresponding to the Yangians of super-algebras of A type will be described. In a parallel development we shall present the four dimensional gauge theories with the surface defects supporting the (conjecturally) super-Kac-Moody chiral algebras.
