量子场论中的协变技术

Covariant techniques in Quantum Field Theory

Enrique Alvarez, Jesus Anero

摘要:

本文综述了用协变方法进行量子场论计算的一些技术。特别是背景场规范,zeta函数正则化和热核方法突出。文中还详细地计算了热核小真时膨胀的Schwinger-de Witt系数。这项工作报告了恩里克·阿尔瓦雷斯在马德里的IFT-UAM-CSIC上发表的演讲。

英文摘要:

In this paper some techniques useful to perform quantum field theory computations in a covariant manner are reviewed. In particular the background field gauge, the zeta function regularization and the heat kernel approach are highlighted. Some detailed calculations of the Schwinger-de Witt coefficients of the small proper time expansion of the heat kernel are also repeated in detail. This work reports lectures given by Enrique Álvarez at the IFT-UAM-CSIC in Madrid.
