Supersymmetric renormalization group flows
The functional renormalization group equation for the quantum effective action is a powerful tool to investigate non-perturbative phenomena in quantum field theories. We discuss the application of manifest supersymmetric flow equations to the N = 1 Wess-Zumino model in two and three dimensions and the linear O (N ) sigma model in three dimensions in the large- N limit. The former is a toy model for dynamical supersymmetry breaking, the latter for an exactly solvable field theory.
