WebPotts model. The aim of this paper is to obtain fluctuation correc tions to mean-field theory in crossover behavior due to spin anisotropy in the p-state Potts model, which amounts to … WebWe present the results of Monte Carlo simulations of two different Potts glass models with short range random interactions. In the first model a \\pm J-distribution of the bonds is chosen, in the second model a Gaussian distribution. In both cases the first two moments of the distribution are chosen to be J_0=-1, Delta J=+1, so that no ferromagnetic ordering of …

Filled diamonds indicate that the model exists and is nontrivial (not mean field), while empty diamonds indicate the dimensions for which there is the onset of mean-field critical exponents (logarithmic corrections to scaling). ... WebAs a simple model of an anisotropic orientational glass with short range forces, the 3-state Potts model on the simple cubic lattice with nearest neighbor interactions drawn from a Gaussian distribution is considered. With Monte Carlo methods we study the response of the system to a uniform “field” which favors one of the states. This is motivated by … ctv horaire

Web1 Jun 2001 · It is demonstrated that the weight of conflict of evidence can, as an approximation, be linearized and mapped to an antiferromagnetic Potts spin model, which facilitates efficient numerical solution, even for large problem sizes. Abstract In this article we investigate a problem within Dempster–Shafer theory where 2q−1 pieces of evidence … WebUsing large scale Monte Carlo simulations, the ordering of the three-dimensional three state Potts ferromagnet exposed to random fields is investigated. Studies of the order parameter probability distribution and of various of its moments suggest that the order of the transition depends on the strength of the random field: i.e., the first order transition of the pure …
