Universality and multifractal behaviour of spin-spin correlation functions in disordered Potts models
Christophe Chatelain, Bertrand Berche
We report a transfer matrix study of the random bond state Potts model in the vicinity of the Ising model . We draw attention to a precise determination of magnetic scalin…
Critical Behavior of the Random Potts Chain
Enrico Carlon, Christophe Chatelain, Bertrand Berche
We study the critical behavior of the random q-state Potts quantum chain by density matrix renormalization techniques. Critical exponents are calculated by scaling analysis of fini…
Boundary critical behaviour of two-dimensional random Potts models
Gábor Palágyi, Christophe Chatelain, Bertrand Berche +1
We consider random q-state Potts models for on the square lattice where the ferromagnetic couplings take two values with equal probabilities. For any q the…
Magnetic critical behavior of two-dimensional random-bond Potts ferromagnets in confined geometries
Christophe Chatelain, Bertrand Berche
We present a numerical study of 2D random-bond Potts ferromagnets. The model is studied both below and above the critical value which discriminates between second and first…
