对数共形场论:导论之外

Logarithmic Conformal Field Theory: Beyond an Introduction

Thomas Creutzig, David Ridout

摘要:

本文旨在回顾对数共形场论中的一些中心主题和例子。它从一个纯粹的Virasoro例子--临界渗流开始,然后详细地阐述了辛费米子,SL(2;R)上的分数阶WZW模型和Lie超群GL(1)上的WZW模型|1)。它的结论是一般性的讨论,所谓的交错模块,使这些理论的对数结构,然后概述了一个建议的战略,以了解更一般的对数共形场论。在整个过程中,重点是连续统的方法和他们的推广,从熟悉的理性的情况。特别是,模块化属性的字符的频谱起着核心作用和Verlinde公式进行评估的结果相比,已知的融合规则。构造了体模不变量,阐明了相应的体状态空间的结构,并讨论了计算关联函数的形式。

英文摘要:

This article aims to review a selection of central topics and examples in logarithmic conformal field theory. It begins with a pure Virasoro example, critical percolation, then continues with a detailed exposition of symplectic fermions, the fractional level WZW model on SL(2;R) at level -1/2 and the WZW model on the Lie supergroup GL(1|1). It concludes with a general discussion of the so-called staggered modules that give these theories their logarithmic structure, before outlining a proposed strategy to understand more general logarithmic conformal field theories. Throughout, the emphasis is on continuum methods and their generalisation from the familiar rational case. In particular, the modular properties of the characters of the spectrum play a central role and Verlinde formulae are evaluated with the results compared to the known fusion rules. Moreover, bulk modular invariants are constructed, the structures of the corresponding bulk state spaces are elucidated, and a formalism for computing correlation functions is discussed.
