Textbook: We will use Prof. Gunion's lecture notes. You can find them at
http://higgs.ucdavis.edu/gunion/QFT-I.pdf and
http://higgs.ucdavis.edu/gunion/QFT-II.pdf.
The lecture notes are nicely written and allow a smooth connection to 230BC for the next 2 quarters as they will be taught by Prof. Gunion. The 230A part of the lecture notes follows mostly the Quantum Field Theory book by Mandl and Shaw, which is one of the easiest field theory book to read. However, you probably don't need to buy this book, instead, I would suggest that you own a copy of ``An Introduction to Quantum Field Theory'' by Peskin and Schroeder. It's a better reference as it's more complete and written from a modern point of view. It is probably the most widely used text book on this subject nowadays. The materials covered in 230A roughly correspond to the first five chapters of Peskin & Schroeder's book. There are also many other quantum field theory books on the market with different approaches and emphases. It is a huge and difficult subject and you won't be able to learn everything from a single book and neither can we cover everthing in one year of the course sequence. In order to have a deeper and broader understanding of this subject, you should not be satisfied with what you learn in the classes and you should keep on learning by yourself even after finishing the course sequence, especially for the students who plan to do theory researches.

Because most of you haven't taken 215C, I'll start with an introduction of relativistic quantum mechanics for the first few classes. The standard textbook for this subject is Bjorken and Drell, ``Relativistic Quantum Mechanics.'' However, it contains materials much more than one can cover for a whole quarter. We will only have time to learn the basic ideas of the Klein-Gordon and Dirac equations. Other useful books are ``Advanced Quantum Mechanics'' by Sakurai and ``Intermediate Quantum Mechanics'' by Bethe and Jackiw. There are also many useful and free notes on the web which you can find with Google. In particular, the Chapter 10 of Quantum Mechanics lecture notes of Prof. Schulten of UIUC is useful for this part of the course and they can be found at
http://www.ks.uiuc.edu/Services/Class/PHYS480/qm_PDF/chp10.pdf
Prof. Berg's (FSU) notes on Special Relativity and Maxwell Equations are useful for the first class as a summary of special relativity needed in this course,

Notes for 4/17 class: Foldy-Wouthuysen Transformation

Grading: There will be homework assignments. Doing the problem sets is an extremely important part of learning. You can't learn the subject by just listening to the lectures without working through things by yourself. You can discuss the problem sets with your classmates, but you are not allowed to copy other people's homework. Each of you is required to write up your own homework following your own understandings. Each problem set is due about one week after its assignment. (The due date will be indicated on the problem set.) No credit will be given after the deadline (so even if you couldn't finish you should turn in what you have done). The homework will constiture 60% of the final grade. There will be a take-home final exam. You have to work on your own and are not allowed to discuss with other people for the final exam. The final exam will constitute 40% of your final grade.
