二维量子场模型(及其在统计力学中的应用)

Two-dimensional Quantum Field Models (with applications to Statistical Mechanics)

Pierluigi Falco

摘要:

二维的玩具模型在一个温和的环境中展示了量子场论的许多突出方面。在这里,我讨论了一个具体的二维情况下,Thirring模型,它说明了这个理论的几个重要概念:异常尺寸的字段;准确的可解性;异常的沃德-高桥身份。此外,我还对这个模型在统计力学的二维格点系统的相关临界指数的研究中所起的决定性作用作了一个粗略的介绍。

英文摘要:

Two dimensional toy models display, in a gentler setting, manysalient aspects of Quantum Field Theory. Here I discuss a concrete two dimensional case, the Thirring model, which illustrates several important concepts of this theory: the anomalous dimension of the fields; the exact solvability; the anomalies of the Ward-Takahashi identities. Besides, I give a glimpse of the decisive role that this model plays in the study of an apparently unrelated topic: correlation critical exponents of two dimensional lattice systems of Statistical Mechanics.
