Strong disorder renormalization group on fractal lattices: Heisenberg models and magnetoresistive effects in tight binding models
R. Mélin, B. Douçot, F. Iglói
We use a numerical implementation of the strong disorder renormalization group (RG) method to study the low-energy fixed points of random Heisenberg and tight-binding models on dif…
Disorder induced rounding of the phase transition in the large q-state Potts model
M. T. Mercaldo, J-Ch. Anglès d'Auriac, F. Iglói
The phase transition in the q-state Potts model with homogeneous ferromagnetic couplings is strongly first order for large q, while is rounded in the presence of quenched disorder.…
Phase transition in the 2d random Potts model in the large-q limit
J-Ch. Angles d'Auriac, F. Igloi
Phase transition in the two-dimensional -state Potts model with random ferromagnetic couplings in the large-q limit is conjectured to be described by the isotropic version of th…
Optimal Cooperation and Submodularity for Computing Potts' Partition Functions with a Large Number of State
J-Ch. Angles d'Auriac, F. Igloi, M. Preissmann +1
The partition function of the q-state Potts model with random ferromagnetic couplings in the large-q limit is generally dominated by the contribution of a single diagram of the hig…
Critical behaviour near multiple junctions and dirty surfaces in the two-dimensional Ising model
F. Igloi, L. Turban, B. Berche
We consider m two-dimensional semi-infinite planes of Ising spins joined together through surface spins and study the critical behaviour near to the junction. The m=0 limit of the…
Two-dimensional Dilute Ising Models: Defect Lines and the Universality of the Critical Exponent ν
Ferenc Szalma, Ferenc Igloi
We consider two-dimensional Ising models with randomly distributed ferromagnetic bonds and study the local critical behavior at defect lines by extensive Monte Carlo simulations. B…
