Résumé |
We will discuss the phase transition in the Ising model with magnetic impurities. By one kind
of lore, this leads to a
non-unitary supersymmetric CFT with scalar supercharges (Parisi-Sourlas supersymmetry).
By further lore, Parisi-
Sourlas SCFT in D dimensions is equivalent to a non-SUSY CFT in D-2 dimensions. It is known
that this story is not fully
correct, but we will put at least some of it on firmer ground using non-perturbative CFT
methods. Joint work with
Apratim Kaviraj and Emilio Trevisani.
