Here are some notes and solutions to accompany the book *Student Friendly Quantum Field Theory* by Robert D. Klauber (Sandtrove Press, 2013).

[My apologies for jumping around between an increasing number of quantum field theory books, but I’m looking for one that presents the subject in an understandable way. Klauber’s book looks the most promising, although he treats only quantum electrodynamics (and not the weak or strong interactions) and does it using the canonical quantization approach which seems to be considered somewhat out of date, compared to the path integral formulation. However, I’m just looking for a relatively easy way into the subject at present and hopefully once I’ve got that, the other books will become more accessible.]

If anyone knows of a truly introductory book on QFT, please do leave a comment.

SandrossTry Advanced Quantum Mechanics by Francis Schawbl. It starts from Non-Relativistic System of Many Particles, why it fails then moves into Relativistic Formulation and then swiftly moves into description of Relativistic Fields. It’s easy to follow the book and almost everything is pretty much worked out or the hints are provided as to how to proceed.

gwrowePost authorThanks for the recommendation. I’ll have a look at Schwabl’s book.
