论文摘要
铁电特性的宏观建模通常是指Landau-Ginzburg-Devonshire理论。本文质疑这个术语的有意义，讨论了三位作者对应该是理论的贡献。分析了每项贡献的局限性。在主要文本中，在补充材料中，兰道理论是从异常的角度提出的，从自发对称性破坏和通过Ising模型完成的简单机械模型开始。演讲的目的是强调与上述三位作者相关的宏观建模的近似特征。
Macroscopic modelling of ferroelectric properties refers usually to Landau-Ginzburg-Devonshire theory. This paper questions the meaningfulness of this term, discussing contributions of the three authors to what is supposed to be a theory. The limitations of every contribution are analyzed. In the main text and, to more extent in the Supplementary Material, the Landau theory is presented from an unusual perspective starting from simple mechanical models of spontaneous symmetry breaking and finishing by the Ising model. The aim of the presentation is to emphasize along with the qualitative breakthroughs the approximate character of macroscopic modelling associated with the above three authors.
