序参量的概率分布函数:混合场与普适性

Probability Distribution Function of the Order Parameter: Mixing Fields and Universality

J. A. Plascak, P. H. L. Martins

摘要:

我们简要地回顾了使用序参量概率分布函数作为一个有用的工具,以获得临界性能的统计力学模型,使用计算机蒙特卡罗模拟。一些简单的离散自旋磁系统的晶格,如伊辛,一般的自旋$S$ Blume-Capel和Wu,$Q$ -态Potts,以及其他模型,将被视为例子。混合场在非对称磁模型中的作用的重要性和必要性将被更详细地讨论,以及相应的广泛的共轭变量的分布。

英文摘要:

We briefly review the use of the order parameter probability distribution function as a useful tool to obtain the critical properties of statistical mechanical models using computer Monte Carlo simulations. Some simple discrete spin magnetic systems on a lattice, such as Ising, general spin-$S$ Blume-Capel and Baxter-Wu, $Q$-state Potts, among other models, will be considered as examples. The importance and the necessity of the role of mixing fields in asymmetric magnetic models will be discussed in more detail, as well as the corresponding distributions of the extensive conjugate variables.
