Selfduality for coupled Potts models on the triangular lattice
Jean-Francois Richard, Jesper Lykke Jacobsen, Marco Picco
We present selfdual manifolds for coupled Potts models on the triangular lattice. We exploit two different techniques: duality followed by decimation, and mapping to a related loop…

Scale Invariance and Self-averaging in disordered systems
Giorgio Parisi, Marco Picco, Nicolas Sourlas
In a previous paper we found that in the random field Ising model at zero temperature in three dimensions the correlation length is not self-averaging near the critical point and t…

A Study of Cross-Over Effects For The 2D Random Bond Potts Model
Marco Picco
We present results of a numerical simulation of the -state random bond Potts model in two dimensions and for large . In particular, care is taken to study the crossover from…
