No-Nonsense Quantum Field Theory: A Student-Friendly Introduction (Paperback)

Learning quantum field theory doesn't have to be hard

What if there were a book that allowed you to see the whole picture and not just tiny parts of it?

Thoughts like this are the reason that No-Nonsense Quantum Field Theory now exists.

What will you learn from this book?

• Get to know all fundamental concepts - Grasp what a quantum field is, why we use propagators to describe its behavior, and how Feynman diagrams help us to make sense of field interactions.
• Learn to describe quantum field theory mathematically - Understand the meaning and origin of the most important equations: the Klein-Gordon equation, the Dirac equation, the Proca equation, the Maxwell equations, and the canonical commutation/anticommutation relations.
• Master important quantum field theory interactions - Read fully annotated, step-by-step calculations and understand the general algorithm we use to particle interactions.
• Get an understanding you can be proud of -Learn about advanced topics like renormalization and regularization, spontaneous symmetry breaking, the renormalization group equations, non-perturbative phenomena, and effective field models.

No-Nonsense Quantum Field Theory is one the most student-friendly book on quantum field theory ever written.

Here's why.

• First of all, it's nothing like a formal university lecture. Instead, it's like a casual conservation with a more experienced student. This also means that nothing is assumed to be "obvious" or "easy to see".
• Each chapter, each section, and each page focuses solely on the goal to help you understand. Nothing is introduced without a thorough motivation and it is always clear where each equation comes from.
• The book ruthlessly focuses on the fundamentals and makes sure you'll understand them in detail.

The primary focus on the readers' needs is also visible in dozens of small features that you won't find in any other textbook

• In total, the book contains more than 100 illustrations that help you understand the most important concepts visually.
• In each chapter, you'll find fully annotated equations and calculations are done carefully step-by-step. This makes it much easier to understand what's going on.
• Whenever a concept is used that was already introduced previously there is a short sidenote that reminds you where it was first introduced and often recites the main points.
• In addition, there are summaries at the beginning of each chapter that make sure you won't get lost.

學習量子場論不必困難

如果有一本書能讓你看到整個畫面而不僅僅是其中一小部分，那該有多好？

正是出於這樣的想法，才有了《No-Nonsense量子場論》。

這本書能讓你學到什麼？

- 瞭解所有基本概念：掌握量子場是什麼，為什麼我們使用傳播子來描述其行為，以及費曼圖如何幫助我們理解場的相互作用。
- 學會以數學方式描述量子場論：理解最重要的方程的含義和起源，包括克萊因-戈登方程、狄拉克方程、普羅卡方程、麥克斯韋方程和規範交換/反交換關係。
- 掌握重要的量子場論相互作用：閱讀完全註釋、逐步計算的過程，並理解我們用於粒子相互作用的一般算法。
- 獲得令人自豪的理解：學習關於諸如重整化和正規化、自發對稱破缺、重整化群方程、非微擾現象和有效場模型等高級主題。

《No-Nonsense量子場論》是有史以來最適合學生的量子場論書籍之一。

原因如下：

- 首先，它完全不像正式的大學講座。相反，它更像是與一位經驗豐富的學生進行的隨意對話。這也意味著不會假設任何事情是“明顯的”或“容易理解的”。
- 每個章節和每個頁面都專注於幫助你理解的目標。沒有任何東西是沒有充分動機介紹的，每個方程的來源都清晰明確。
- 這本書無情地專注於基礎知識，並確保你能詳細理解它們。

對讀者需求的主要關注也體現在數十個其他教科書中找不到的小功能中：

- 整本書共包含100多個插圖，幫助你以視覺方式理解最重要的概念。
- 每個章節都有完全註釋的方程，計算過程都仔細逐步進行。這使得理解正在發生的事情變得更容易。
- 每當使用先前介紹過的概念時，都會有一個簡短的旁注提醒你它最初是在哪裡介紹的，並經常重述主要觀點。
- 此外，每個章節開始時都有摘要，確保你不會迷失方向。
