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…
Random energy levels and low-temperature expansions for spin glasses
M. Picco, F. Ritort, M. Sales
In a previous paper (cond-mat/0106554) we showed the existence of two new zero-temperature exponents (λand θ') in two dimensional Gaussian spin glasses. Here we introduce a novel l…
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…
Correlation functions for the 2D random bonds Potts Models
Vladimir Dotsenko, Marco Picco, Pierre Pujol
We study the spin-spin and energy-energy correlation functions for the 2D Ising and 3-states Potts model with random bonds at the critical point. The procedure employed is the reno…
