Weighted mean-field theory for the random field Ising model

David Lancaster, Enzo Marinari, Giorgio Parisi A

Published Jul 21, 1995• 21 citations

Abstract

We consider the mean-field theory of the random field Ising model obtained by weighing the many solutions of the mean-field equations with Boltzmann-like factors. These solutions are found numerically in three dimensions and we observe critical behaviour arising from the weighted sum. We estimate the exponents.

Fluctuations in the random-field Ising model

Terufumi Yokota

Fluctuations can break down mean-field critical behaviour. For the random-field Ising model, fluctuations caused by the randomness are important. The Ginzburg criteria based on two kinds of mean-field theory are discussed. One is the mean-field theory using the replica method and the other is the site-dependent mean-field theory. An argument that justifies the use of the site-dependent mean-field theory to obtain critical properties for the random-field Ising model is given.

Critical exponents of the pure and random-field Ising models

Th. Jolicœur, Jean-Claude Le Guillou

We show that current estimates of the critical exponents of the three-dimensional random-field Ising model are in agreement with the exponents of the pure Ising system in dimension $3\ensuremath{-}\ensuremath{\theta}$ where \ensuremath{\theta} is the exponent that governs the hyperscaling violation in the random case.

Randomly dilute Ising model: A nonperturbative approach

Matthieu Tissier, D. Mouhanna, Julien Vidal +1 more

The N-vector cubic model relevant, among others, to the physics of the randomly dilute Ising model is analyzed in arbitrary dimension by means of an exact renormalization-group equation. This study provides a unified picture of its critical physics between two and four dimensions. We give the critical exponents for the three-dimensional randomly dilute Ising model that are in good agreement with experimental and numerical data. The relevance of the cubic anisotropy in the $O(N)$ model is also treated.

Scaling above the upper critical dimension in Ising models

Giorgio Parisi A, Juan Jesus Ruiz-Lorenzo

We rederive the finite-size scaling formula for the apparent critical temperature by using mean-field theory for the Ising model above the upper critical dimension. We have also performed numerical simulations in five dimensions and our numerical data are in good agreement with the mean-field theoretical predictions, in particular, with the finite-size exponent of the connected susceptibility and with the value of the Binder cumulant.

Critical behaviour of the random field Ising model

Jean-Yves Fortin, P. C. W. Holdsworth

We present an analytic real-space renormalization group calculation for the random-field Ising model. We apply the Migdal-Kadanoff approximation for the renormalization of a cubic cell in dimensions d , introducing a new field partitioning scheme which allows us to treat the random-field fluctuations in a coherent manner. Our scheme leads naturally to a lower critical dimensionality and allows us to calculate a complete set of three independent exponents in arbitrary dimension. In three dimensions the magnetization exponent and the Schwartz-Soffer inequality is almost satisfied as an equality. We expand analytically in . Further, we show that and the magnitude of the inequality go to zero exponentially with . We calculate the crossover exponent, from pure to the random-field system and find surprisingly good agreement with experimental values. We find that satisfies the Schwartz-Soffer inequality: , the susceptibility exponent of the pure system. We expand in and find that the magnitude of the inequality varies exponentially in . Finally we find that dimensional reduction is satisfied to first order in , with the reduced dimension .

THEORY OF THE RANDOM FIELD ISING MODEL

Thomas Nattermann

A review is given on some recent developments in the theory of the Ising model in a random field. This model is a good representation of a large number of impure materials. After a short repetition of earlier arguments, which prove the absence of ferromagnetic order in $d\le 2$ space dimensions for uncorrelated random fields, we consider different random field correlations and in particular the generation of uncorrelated from anti-correlated random fields by thermal fluctuations. In discussing the phase transition, we consider the transition to be characterized by a divergent correlation length and compare the critical exponents obtained from various methods (real space RNG, Monte Carlo calculations, weighted mean field theory etc.). The ferromagnetic transition is believed to be preceded by a spin glass transition which manifests itself by replica symmetry breaking. In the discussion of dynamical properties, we concentrate mainly on the zero temperature depinning transition of a domain wall, which represents a critical point far from equilibrium with new scaling relations and critical exponents.
