I will explain a new way to write down a Landau-Ginzburg model for an arbitrary Grassmannian X in terms of Pluecker coordinates on a dual Grassmannian. Our main result is that we obtain integral formulas for the coefficients of Givental's J-function (and more). In proving these formulas we make heavy use of the cluster algebra structure of the Grassmannian and associated combinatorics, of which I will try to give a glimpse.
