Course requirements and grade:
Text:  There are quite a few quantum field theory textbooks that emphasize different aspects of the subject. This course will be loosely based on M. Peskin and D. Schroeder, An Introduction to Quantum Field Theory. Corrections to the textbook are available here. I will also provide lecture notes, which have been influenced by a number of sources, most notably Sidney Coleman's lectures. You can find video of Coleman's lectures online here, and lecture notes for the first semester transcribed by Brian Hill here and here, and typeset here. I also borrow from Mehran Kardar's Statistical Physics of Fields. David Tong's lecture notes are excellent. Steven Weinberg's three-book series The Quantum Theory of Fields contains insights not found in other textbooks, and is a useful reference. Matthew Schwartz's book, Quantum Field Theory and the Standard Model, is also excellent.
Homework will be assigned roughly weekly on Thursdays, and due the following Thursday. Problem sets will be available on Blackboard.
