### REQUIRED TEXTBOOK

"Principles of Quantum Mechanics" by R. Shankar, 2d edition, Springer 1994. We will cover chapters 17 - 21.There are many other useful textbooks on quantum mechanics. You are encouraged to explore alternatives. Here are four that are commonly used in graduate level courses:

- L. Landau and E. Lifchitz `Quantum Mechanics', Pergamon Press.
- L.I. Schiff `Quantum Mechanics', 3d Edition, McGraw-Hill 1968.
- E. Merzbacher `Quantum Mechanics', 2d Edition, Wiley 1970.
- J.J. Sakurai `Modern Quantum Mechanics', Addison-Wesley 1985.

### COURSE OUTLINE

- Time-independent perturbation theory
- Selection rules
- Time-dependent perturbation theory
- Scattering theory
- Time reversal symmetry
- Motion in a periodic potential

### CLASS ATTENDANCE

Requirements for class attendance, make-up exams, and other work in this course are consistent with university policies that can be found at**https://catalog.ufl.edu/ugrad/current/regulations/info/attendance.aspx**.

### ACCOMMODATIONS FOR STUDENTS WITH DISABILITIES

Students with disabilities requesting accommodations should first register with the Disability Resource Center (352-392-8565,**https://www.dso.ufl.edu/drc**) by providing appropriate documentation. Once registered, students will receive an accommodations letter which must be presented to the instructor when requesting accommodation. Students with disabilities should follow this procedure as early as possible in the semester.

### COURSE EVALUATIONS

Students are expected to provide feedback on the quality of instruction in this course by completing online evaluations at**https://evaluations.ufl.edu**. Evaluations are typically open during the last two or three weeks of the semester, but students will be given specific times when they are open. Summary results of these assessments are available to students at
