The Department of Physics offers a twosemester long sequence of graduate level
Quantum Mechanics, Physics 580 and Physics 581. Both courses are essentially
thought of as a single course,
with Physics 580 covering the basic material and Physics 581 the more
advanced topics. This is the continuation of the year long course on Quantum
Mechanics. I taught part I in the Fall Semester, 2017. I will assume that you
are familiar with what I taught in Physics 580.
Course Plan
Time Evolution of Observables and Time Dependent perturbation Theory
Heisenberg and Schrödinger pictures. The evolution operator. Time ordered
products. Timedependent perturbation theory. Fermi's Golden Rule. Applications.
Spin
The group of rotations and its representations. Integer and half integer
representations. Rotations in spin space. Spin wave functions. Spin
Hamiltonians. SpinOrbit Interaction. Spin Precession and Spin Resonance.
Adiabatic processes and Berry phases. Coherent state path integrals and the path integral for spin
Theory of Angular Momentum and the Rotation Group in Quantum Mechanics
Addition of angular momenta. ClebschGordan coefficients. ClebschGordan methods.
Applications. Scattering of distinguishable particles with spin. Rotation and tensor operators.
The WignerEckart Theorem and applications.
Identical Particles,
MultiParticle Systems and Second Quantization

Syllabus for Quantum Mechanics I,
Physics 580, Fall Semester 2017
Grades
There will be a total of six (6) homework sets;
the final set will play the role of the (take home) final exam.
The final exam will have the same
weight (1/6) as any of the other homework sets. However, since it is the Final Exam
you must take it or otherwise you will not be able to pass this class. The homework sets are
due on the due date posted on this webpage and have to be deposited at the
Physics 581 Homework Box (at the Loomis end of the LoomisMRL Interpass,
second floor), before midnight on that date. There will be a 20%
grade penalty on late homework sets and no homework sets will be accepted of they are
more than two days late (barring extenuating circumstances which will only be
considered by the Instructor, not by the TA.)
You may check your grades by looking at your entry in the
Physics 581 Gradebook

Note: This is a takehome Final Exam. The solutions must send me by email (to efradkin@illinois.edu) the pdf file with your solutions before Friday 5/11/2018 at 5:00pm.
You should not give the solutions to the TA nor put them in the Physics 581 homework box.
No late sets will be accepted. Since this problem set is a take home Final Exam, you must turn in your solutions to pass this course. You must make sure that the pdf file is clearly legible!.
Please either prepare the solutions in LaTeX . If your solutions are handwritten you must write them with dark pen with clearly legible handwriting in double spaced paper. I cannot grade solutions with bad handwriting and/or with random organization. They must be clearly organized with your results shown clearly.
