具有类偶极相互作用的随机场Potts模型:滞后、雪崩和微观结构

Random Field Potts model with dipolar-like interactions: hysteresis, avalanches and microstructure

Benedetta Cerruti, Eduard Vives

摘要:

本文提出了一个研究从单变量相到多变量相的一阶相变中的滞后和雪崩的模型。该模型是基于修改后的随机场波茨模型与亚稳态动力学通过添加一个偶极相互作用项截断在最近的邻居。我们的研究重点是磁滞回线特性,三维(3D)微结构的形成和雪崩统计。

英文摘要:

A model for the study of hysteresis and avalanches in a first-order phase transition from a single variant phase to a multivariant phase is presented. The model is based on a modification of the Random Field Potts model with metastable dynamics by adding a dipolar interaction term truncated at nearest neighbors. We focus our study on hysteresis loop properties, on the three-dimensional (3D) microstructure formation and on avalanche statistics.
