商品描述

An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.

商品描述(中文翻譯)

《量子場論入門》是一本教科書,旨在為研究生物理課程提供相對論量子力學、量子電動力學和費曼圖的內容。作者通過精心設計的例子展示了這些主題的技術層面,並通過直觀的解釋揭示了數學背後的原理。在介紹了量子電動力學的基礎知識後,作者討論了重整化理論及其與統計力學的關係,並引入了重整化群。這一討論為探討基本粒子物理的基本相互作用原理以及其在規範場論中的描述奠定了基礎。
