Nonperturbative Functional Renormalization Group for Random Field Models. III: Superfield formalism and ground-state dominance

Understand

We reformulate the nonperturbative functional renormalization group for the random field Ising model in a superfield formalism, extending the supersymmetric description of the critical behavior of the system first proposed by Parisi and Sourlas [Phys.
