The fate of Parisi-Sourlas supersymmetry in Random Field models
Apratim Kaviraj, Slava Rychkov, Emilio Trevisani
By the Parisi-Sourlas conjecture, the critical point of a theory with random field (RF) disorder is described by a supersymmeric (SUSY) conformal field theory (CFT), related to a $…

Random Field Ising Model and Parisi-Sourlas Supersymmetry. Part II. Renormalization Group
Apratim Kaviraj, Slava Rychkov, Emilio Trevisani
We revisit perturbative RG analysis in the replicated Landau-Ginzburg description of the Random Field Ising Model near the upper critical dimension 6. Working in a field basis with…
