Revisiting a low-dimensional model with short range interactions and mean field critical behavior
نویسندگان
چکیده
In all local low-dimensional models, scaling at critical points deviates from mean field behavior -- with one possible exception. This exceptional model ``ordinary" is an inherently non-equilibrium studied some time ago by H.-M. Broker and myself. simulations, its 2-dimensional version suggested that two exponents were mean-field, while a third showed very small deviations. Moreover, the numerics agreed almost perfectly explicit model. present paper we simulations much higher statistics, both for 2d 3d. cases find deviations of their values are non-leading corrections, {\it precisely} type. As in original paper, propose mechanism this ``confusion", strong randomization phases feed-backs can occur systems.

Boundary between long-range and short-range critical behavior in systems with algebraic interactions.
We investigate phase transitions of two-dimensional Ising models with power-law interactions, using an efficient Monte Carlo algorithm. For slow decay, the transition is of the mean-field type; for fast decay, it belongs to the short-range Ising universality class. We focus on the intermediate range, where the critical exponents depend continuously on the power law. We find that the boundary wi...
متن کاملOne-dimensional Ising model with long-range and random short-range interactions
The one-dimensional Ising model in an external magnetic field with uniform long-range interactions and random short-range interactions satisfying bimodal annealed distributions is studied. This generalizes the random model discussed by Paladin et al. (J. Phys. I France 4, 1994, p. 1597). Exact results are obtained for the thermodynamic functions at arbitrary temperatures, and special attention ...
متن کاملExistence and Uniqueness for a Dislocation Model with Short-range Interactions and Varying Stress Field
In this article, we consider a coupled singular parabolic system, describing the dynamics of dislocation densities in a bounded domain. The model takes into consideration the short-range interactions between dislocations, which causes the singularity that appears under the form of dividing by a gradient term. We prove a long time existence and uniqueness under the assumption that the applied st...
متن کاملMean-field expansion for spin models with medium-range interactions
We study the critical crossover between the Gaussian and the Wilson-Fisher fixed point for general O(N)-invariant spin models with medium-range interactions. We perform a systematic expansion around the mean-field solution, obtaining the universal crossover curves and their leading corrections. In particular we show that, in three dimensions, the leading correction scales as R−3, R being the ra...
متن کاملClassical critical behavior of spin models with long-range interactions
We present the results of extensive Monte Carlo simulations of Ising models with algebraically decaying ferromagnetic interactions in the regime where classical critical behavior is expected for these systems. We corroborate the values for the exponents predicted by renormalization theory for systems in one, two, and three dimensions and accurately observe the predicted logarithmic corrections ...
