PY4106: Quantum Field Theory

Dr. Asaf Pe'er

Course Schedule


Quantum field theory (QFT) is the theoretical framework that forms the basis for the modern description of sub-atomic particles and their interactions, as well as modern statistical physics. It was born by a merge of quantum mechanics and special relativity. As such, the material taught in this course relies on a number of previous courses, both in physics and mathematics. These include: (I) Lagrangian mechanics; (II) quantum mechanics; (III) special relativity; (IV) Fourier transforms; (V) Dirac delta function; and (VI) functions of complex variables. Here you can find a short summary (which is by no means complete !) of the pre-requests. If you are not comfortable with any of these concepts or terms, you should review a suitable book as soon as possible.

Course Syllabus

Lecture notes

Important Note. These are my personal lecture notes, that I prepared for my personal use as part of the preparations for teaching this module. I post them here for the sole purpose of assisting the students learning this fascinating, yet difficult subject.
I make no claim of originality. I am basing a large part of the text on the lecture notes of David Tong, which are freely available here. Other major resources I used are the books by Michael Peskin and Daniel Schroeder and, to a lesser extent, by Steven Weinberg, Lewis Ryder and Anthony Zee. I also used my personal notes from the courses taught by Yosef Nir, and by Adam Schwimmer.



  • The final exam is schedule for Monday, April 25th, 2016.
    This is a closed book exam. You will be asked to solve 2 questions out of 3 options.
    Naturally, the questions will represent the material studies in class and in homework.
  • It is aimed at checking your understanding. You will not be asked to calculate long derivatives, but you are required to be familiar with the basic concepts and to be able to do basic calculations (e.g., basic Feynman diagrams, etc.).
  • As usual, your best indication about how well you are predicted to do in the exam is how well you do in homework - if you are able to solve the problems yourself, you need not worry.

Good Luck !!
