Student Evaluation
- Standard A to F grading system. Grading will depend on performance in periodic problem sets, a midterm exam and a final exam, with the following weights:
- Homework: 40%
- Midterm exam: 30%
- Final exam: 30%
Homeworks
By all means you may work in groups on the homework assignments. Collaboration is an important part of learning and of scholarship in general. However, each student must turn in her or his own writeup of the solutions. If two individual writeups are nearly identical, neither will receive credit. In fairness to your fellow students, late homework will not be accepted.
Description
This is the second part of the introductory course on Quantum Mechanics for first year Physics graduate students. The main topics to be discussed are: Time-independent and time-dependent perturbation methods, scattering theory, radiative decays of atoms, systems of identical particles, spin and statistics.
Objectives
After completing this course the student will have a good background to carry out basics quantum mechanical calculations in systems of practical interest.
