Introduction to the gauge/Bethe correspondenceTBA

In this seminar I will introduce the correspondence between quantum integrable models and two-dimensional supersymmetric gauge theories discovered by Nekrasov and Shatashvili. In this correspondence the Yang-Yang functional, which generates the Bethe equations of the quantum system, is the effective twisted superpotential of the gauge theory. I will also show how one can associate a classical mechanical model to the quantum integrable model, such that the Yang-Yang functional is the generating function of a Lagrangian submanifold.
