Description
I will discuss the critical physics of a class of disordered (impure) quantum field theories, called random field models. An interesting example comes from 'branched polymers' whose critical properties are described by the random field phi^3 model. Parisi and Sourlas conjectured nearly 40 years ago that these models have a critical point characterized by an emergent supersymmetry and a mysterious 'dimensional reduction' property. In numerical simulations one finds that the conjecture works only under certain conditions. I will demonstrate how this connection works from a textbook like RG flow analysis of random field models.
