自举思想在共形场论中的应用
Bootstrap ideas in conformal field theories

摘要:
“自举”最早起源于20世纪60年代对强子的研究,研究者试图仅通过系统的自洽性来定量地理解复杂的强相互作用。尽管这种尝试最终没能取得成功,自举的思想却被保留了下来,并逐渐发展为研究强耦合量子场论的一个重要工具。文章将简单介绍自举思想及其在共形场论研究中的一些应用。

Abstract:The bootstrap idea originated in the study of hadrons in the 60’s where researchers tried to derive a quantitative understanding of the complicated strong interaction from only consistency conditions. While this attempt failed, the bootstrap philosophy survived, and has now become a powerful way to understand strongly coupled quantum field theories. In this article, I will briefly discuss the ideas of bootstrap and their applications in studying conformal field theories.
