微扰共形场论的解析自助法

Analytic Bootstrap for Perturbative Conformal Field Theories

Johan Henriksson

摘要:

共形场论在理论物理学中起着核心作用,其应用范围从凝聚态到弦论。共形引导法利用数学相容性条件研究共形场论,在过去的十年里取得了很大的进展。在这篇论文中,我们将大自旋微扰理论与洛伦兹反演公式相结合,提出了一种求解二维以上微扰共形场论的解析自举方法。在一个小的膨胀参数的存在下,不一定是耦合常数,我们发展成一个系统的框架,适用于广泛的理论。前两章提供了必要的背景知识,并回顾了分析引导法。接下来的一章详细描述了该方法,通过逐步实现的方式,以实用指南的形式介绍了大自旋微扰理论。论文的第二部分提出了几个明确的实现框架,从一些研究良好的共形场论的例子。我们展示了有多少文献结果可以从一个纯粹的自举的角度来复制,以及如何可以得出各种新的结果。

英文摘要:

Conformal field theories play a central role in theoretical physics with many applications ranging from condensed matter to string theory. The conformal bootstrap studies conformal field theories using mathematical consistency conditions and has seen great progress over the last decade. In this thesis we present an implementation of analytic bootstrap methods for perturbative conformal field theories in dimensions greater than two, which we achieve by combining large spin perturbation theory with the Lorentzian inversion formula. In the presence of a small expansion parameter, not necessarily the coupling constant, we develop this into a systematic framework, applicable to a wide range of theories. The first two chapters provide the necessary background and a review of the analytic bootstrap. This is followed by a chapter which describes the method in detail, taking the form of a practical guide to large spin perturbation theory by means of a step-by-step implementation. The second part of the thesis presents several explicit implementations of the framework, taking examples from a number of well-studied conformal field theories. We show how many literature results can be reproduced from a purely bootstrap perspective and how a variety of new results can be derived.
