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. In will teach the advanced
graduate level of Quantum Mechanics, Physics 581, in the Spring semester of the
Academic year 2017/2018. For Physics 580 I will assume that the students are
familiar with Quantum Mechanics at the level of an undergraduate course of the type offered
here. I will also assume that the students are familiar with
the Lagrangian and Hamiltonian descriptions of Classical
Mechanics, say at the level of Landau and Lifshitz and/or Goldstein.
I will assume that the students are
familiar with the fundamental concepts of linear algebra, vector spaces, and
calculus on functions of a complex variable, in particular with the methods of
contour integration and residues, as well as with standard material in partial differential
equations. Much of the necessary background is at the level covered in the MMA and MMB courses
offered here. Students are urged to review this background
material before coming to class. I prepared a set of notes on this material.
Below you will find a link to these notes.

spectrum. The Photoelectric effect. Atomic spectra. Double slit experiments. Particles
and waves.

Syllabus for Quantum Mechanics II,
Physics 581, Spring Semester 2018
Grades
There will be a total of seven (7) homework sets. The last set will be your final exam. The final exam will
weigh 1/7 of the grade and the homework sets the remaining 6/7. The homework sets are
due on the due date posted on this webpage and have to be deposited at the TA's
mailbox 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 580 Gradebook

Note: This is a takehome Final Exam. The solutions must send me by \textbf{email} (to efradkin@illinois.edu) the pdf file with your solutions before Sunday 12/17/2017 at 5:00pm. You should not give the solutions to the TA nor put them in the Physics 580 homework box.
No late sets will be accepted. Please note that 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 or if your solutions are handwritten you must writhe the with dark pen with clearly legible handwriting. I cannot grade solutions with bad handwriting and/or with random organization. They must be clearly organized with your results shown clearly.
