PHY 341: Quantum Field Theory I
This is an introduction to quantum field theory. Quantum
field theory is an indispensable tool for the study
particle, nuclear and condensed matter
physics and has applications to an even broader range
of physical systems. The goal of this course is to introduce the basic
concepts of quantum field theory . Students will learn the techniques
for doing perturbative calculations of elementary processes in QED
and other simple field theories. We also expect to
discuss gauge invariance, path integrals, symmetries and
renormalization. Though most examples will be drawn from
particle physics, I will also include applications
from other areas of physics.

Grading Policy
There will be weekly problem sets and a final exam.
Grades will be assigned according to the following weighted
average:
Problem Sets: 60%
Final exam: 40%
Recommended Reading:
Some other quantum field theory textbooks which you may find
useful are listed below.

F. Mandl and Shaw, G. Quantum Field Theory.
Peskin and Schroeder call this the easiest book on field theory so it maybe
a good place to get help if you are stuck.

L. Ryder, Quantum Field Theory. An elementary discussion
with some advanced topics included.

S. Weinberg, The Quantum Theory of Fields, Vols. III.
We will be covering mostly material in Vol. I.
These are excellent books which emphasize the modern viewpoint of effective field theory.
The notation is quite nonstandard.

C. Itsykson and J.B. Zuber, Quantum Field Theory.
This book is a classic with an extremely thorough treatment of QED. This will
serve as an extremely useful reference.
Comments:

A link to the problem sets is at the bottom of this webpage.
Problem Sets will be assigned every Thursday and are due the following Thursday.
Solutions will be posted shortly thereafter.
 No Late Problem Sets will be accepted!

You are encouraged to discuss the homework assignments with
fellow students so that you can learn the subject from each other. However,
the written part of the homework assignments must be done individually.

Course webpage as well as email will be used to disseminate information on problem set corrections,
class schedule emergencies, etc.
