Reading List
The classic texts on the subject are by Bjorken and Drell, Relativistic Quantum Mechanics and Relativistic Quantum Fields. Everything in the first is worth knowing; the second is somewhat outdated but still worth a look.
There are many good modern textbooks on QFT. None of them exactly coincides with this course, as we progress you will have to move around in the books, and they all contain a lot more material than we can cover in a 24-lecture course. You will probably find it useful to look at more than one book. Unfortunately, there is no universally accepted set of conventions in QFT so for clarity we will use those of:
An Introduction to Quantum Field Theory by Peskin and Schroeder. This is a very large book and covers a great many detailed topics. It will certainly see you through the first year of learning QFT though you may find it rather heavy going.
Some other books that are certainly worth looking at:
Quantum Field Theory by Mandl and Shaw is very clear on the fundamentals and is a good place to start, especially if you are daunted by the size of some of the other books;
Quantum Field Theory by Srednicki focusses on the path integral before canonical quantisation, but from a particle physics point of view covers all the bases.
Quantum Field Theory in a Nutshell by Zee covers a vast range of the subject. If you like relatively condensed presentations then you will like this book.
Statistical Physics of Fields by Kardar approaches the topic from the rather different statistical mechanical point of view. If you are planning to work in condensed matter or statistical physics then you should certainly read this book at some point.
