"Locally self-similar phase diagram of a disordered Potts model on a hierarchical lattice"

The Potts model with bond disorder is studied in the limit of a infinite number of states on a hierarchical lattice. This model is "academical" since neither the hierarchical lattice nor the infinite number of states are really physical. However the final result, ie the phase diagram of the model obtained by renormalization, is unusual and can justify this study.
