瞬子讲座

Lectures on instantons

Stefan Vandoren, Peter van Nieuwenhuizen

摘要:

这是一套完备的关于四维(超)杨-米尔斯理论和量子力学中瞬子的课堂讲稿。首先,从零开始推导基本的理论:规范群SU(2)和SU(N)的杨-米尔斯理论的正则和奇异单瞬子解,它们的玻色子和费米子零模,路径积分瞬子测度,以及欧几里德空间中的超对称杨-米尔斯理论。然后我们讨论应用程序:QCD的θ角,U(1)问题的解,希格斯场解决大瞬子问题的方式,以及量子力学和非阿贝尔规范理论中的隧穿和相变。这些课堂讲稿是作者和A.Belitsky在2000年写的关于Yang-Mills和D-瞬子的评论的延伸

英文摘要:

This is a self-contained set of lecture notes on instantons in (super) Yang-Mills theory in four dimensions and in quantum mechanics. First the basics are derived from scratch: the regular and singular one-instanton solutions for Yang-Mills theories with gauge groups SU(2) and SU(N), their bosonic and fermionic zero modes, the path integral instanton measure, and supersymmetric Yang-Mills theories in Euclidean space. Then we discuss applications: the θ-angle of QCD, the solution of the U(1) problem, the way Higgs fields solve the large-instanton problem, and tunneling and phase transitions in quantum mechanics and in nonabelian gauge theories. These lecture notes are an extension of a review on Yang-Mills and D-instantons written in 2000 by both authors and A.Belitsky
