晶格自旋模型中的反射正性和相变

Reflection positivity and phase transitions in lattice spin models

Marek Biskup

摘要:

反射正性(RP)是一类晶格自旋系统所表现出的吉布斯测度的性质,包括伊辛、波茨和海森堡模型。RP属性是有用的,因为它的两个基本结果:红外边界和棋盘估计。这些是证明物理模型中相变的基本(也是相当有效的)工具之一。本文中的笔记总结了作者于2006年9月在布拉格数学统计力学暑期学校发表的关于反思积极性及其后果的演讲。该文本的特点都是经典材料的主题从20世纪70年代末以及一些最近的事态发展。

英文摘要:

Reflection positivity (RP) is a property of Gibbs measures exhibited by a class of lattice spin systems that include the Ising, Potts and Heisenberg models. The RP property is useful because of its two basic consequences: infrared bound and chessboard estimates. These are one of basic (and rather efficient) tools for proving phase transitions in many models of physical interest. The notes presented hereby summarize the lectures on reflection positivity and its consequences that the author delivered at the Prague Summer School on Mathematical Statistical Mechanics in September 2006. The text features both the classical material on the subject from the late 1970s as well as some of the more recent developments.
