Lahiri & Pal: A First Book of Quantum Field Theory

Here are my notes and solutions to accompany the book A First Book of Quantum Field Theory (Second Edition) by Amitabha Lahiri & P. B. Pal. As always, no guarantees that my solutions are actually correct.

Errata for the book can be found here.

Chapter 1: Preliminaries

1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8

Chapter 2: Classical Field Theory

2.1, 2.2, 2.3

    Why are you starting with many QFT books and then leaving them? Are you having trouble with the compactification of the equations (missing steps etc…)

      Partly that, but mainly because my background in ‘ordinary’ quantum mechanics doesn’t seem to be adequate. There’s a fair gap between the quantum mechanics covered in Griffiths’s book and that assumed by all the QFT books I’ve looked at so far. I’m currently working through Shankar’s Principles of Quantum Mechanics which hopefully will provide the necessary background.
      However, if you do know of any QFT books that are more accessible, please let me know. Thanks.

        I think Klaubers is the best intro to QFT pedagogically. Some people recomend Griffiths “Introduction to Elementary Particles” before starting QFT. And Shankar is a great choice for “graduate” QM as Zettili’s book (again pedagogically). So I think you are in the right track.
