伊辛模型的连续统推广

A Continuum Generalization of the Ising Model

Haley A. Yaple, Daniel M. Abrams

摘要:

Lenz-伊辛模型作为理解铁磁性的基础已经服务了近一个世纪,并且已经成为统计力学中相变的典范模型。在保留伊辛能量参数的同时,我们使用以前应用于社会物理学的技术来提出一个连续统模型。我们的配方的结果在积分微分方程,有几个优势,比传统的版本:它允许渐近分析的相变,材料性能,和动态的磁畴的形成。

英文摘要:

The Lenz-Ising model has served for almost a century as a basis for understanding ferromagnetism, and has become a paradigmatic model for phase transitions in statistical mechanics. While retaining the Ising energy arguments, we use techniques previously applied to sociophysics to propose a continuum model. Our formulation results in an integro-differential equation that has several advantages over the traditional version: it allows for asymptotic analysis of phase transitions, material properties, and the dynamics of the formation of magnetic domains.
