Physics 215a, Quantum Field Theory 2019

Professor: Ken Intriligator, Mayer Hall 5234. Office hours: after class, or stop by.

TA: Zhengdi Sun, Mayer Hall 4430. Office hours: Thursdays, 2:00-3:20, or stop by.

Question and answer session Tuesday Dec 10, MYR-A 2623, 11:00am-noon.

Text: The lectures will largely follow these free, online notes:

  • Sidney Coleman's lectures. Classic videos can be found here . World Scientific made the lectures into a book, but I do not support it because they misguidedly included the solutions to Coleman's classic exercises, which just encourages lazy shortcuts and takes the challenge out of the exercise. Please avoid that.

  • David Tong's beautiful lecture notes Videos can be found here.

  • John McGreevy's beautiful lecture notes .

    Recommended book for advanced QFT topics Coleman's Aspects of Symmetry. I will probably discuss some of the topics there in part III in the Spring.

    Course Times: MW 2:00-3:20pm, MYR-A 2623.

    Final Exam: Wednesday, December 11, 3:00-6:00pm, MHR-A 2623.

    Homework: It is essential to do your exercises. Many of the assigned problems have solutions that can be found online -- try to resist that, it's cheating both yourself, and it is technically, officially cheating. Working together in groups is fine, and encouraged, as long as everyone is working.

    Homework: Homework: 50%, final 50%.
