Exams- Midterm 1 - 21 September
- Midterm 2 - 1 November
- Final Exam - 23 November
Suggested textbooks
Main text - J.J. Sakurai, "Modern Quantum Mechanics"
Other texts - Shankar, Principles of Quantum Mechanics.
- Weinberg, Lectures on Quantum Mechanics
Evaluation
Grades will be based on homework (10%) and the best 2 out of 3 exams (45% each).
The two midterm exams will cover ~50% of the material, and the final exam will review the entire semester. The lowest score of the three exams will be dropped, and the remaining 2 scores will determine 90% of your final grade.
ProgramTentative list of topics: - General structure of quantum mechanics
- Examples
- Angular momentum / spin
- Approximation methods
