PHY6648: Quantum Field Theory I

This course is the first semester of a three semester course on modern quantum field theory and the standard model of elementary particles. Although the course is mandatory for students interested in high energy particle physics, it should also be valuable to students of other specialties including condensed matter physics and atomic and molecular physics. For example, in the first semester we shall develop, in our treatment of the Dirac equation, the technique of second quantization so useful in many body theory. Furthermore, the emphasis of the whole course is on Quantum Electrodynamics, which is essential to an understanding of all areas of physics. Quantum Field Theory I is the natural continuation of the graduate quantum mechanics courses PHY6645-46.

PHZ6358: Standard Model of Elementary Particles I/ Quantum Field Theory II

This course is the second semester of quantum field theory and the standard model. The first part of the course will deal with 1 loop Quantum Electrodynamics (QED) and its renormalization. Then nonabelian gauge theory will be introduced with applications in QCD the gauge theory of strong interactions. The gauge group of the standard model will be presented. Spontaneous breaking of global symmetries will be introduced with first applications to chiral symmetry breaking and pions as Goldstone bosons. Then spontaneous breaking of local (i.e. Gauge) symmetries will be discussed with application to the electroweak sector of the standard model.

PHZ7359: Standard Model of Elementary Particles II and Quantum Field Theory II

Continuation of PHZ6358.

You can access the evaluation form at your leisure from the web site: https://evaluations.ufl.edu/evals/ where you can find instructions and links to a gatorlink login page. It is probably a good idea if you bookmark the page so you can easily find it in the future.

    Homework Assignments

    In the homework assignments, I will refer to problems in Srednicki's book by prefixing the problem number with S. Note that there are many problems in his book which ask the reader to fill in gaps in the preceding discussion (e.g. S 2.1 through 2.7). I will generally not assign such problems to be graded, but you should nonetheless make sure you understand how to do them.

    Information on Final Exam

    In grading the final, points will be deducted for errors in calculation and logic. This is in sharp contrast to the grading of the homework which was based more on the amount of work done than its accuracy. Absolutely no collaboration will be allowed. Each student's exam must be entirely his own work.

    And the end of all our exploring
    Will be to arrive where we started
    And know the place for the first time.
