介观物理系统的量子场论模型一维持续电流的Luttinger模型

QUANTUM FIELD THEORETICAL MODELS FOR MESOSCOPIC SYSTEMS——LUTTINGER MODEL AND PERSISTENT CURRENT

本文以研究生进入选题前水平介绍介观物理系统中的一种重要的量子场论模型和方法。讨论一维介观电子系统的Luttinger模型和非费米液体的特征和基本物理。我们简单介绍重整化群概念和玻色化技术和用于一维Luttinger模型。

Luttinger Model for non-Fermi Liquid of one dimensional mesoscopic systems is described. We introduce the technique of bosonization and the concept of renormalization group method to discuss this model and non_Fermi liquid properties, at a junior graduate student level.
