Quantum Mechanics

This the third quarter of a one year graduate level course. It is for
students who have had an introductory course in quantum mechanics
before. Students should also have a good background in mathematics,
including linear algebra and complex analysis. I will start from the
beginning and develop the major ideas of quantum mechanics. Thus a
student who has not seen some particular idea or method will be able to
learn it in this course. However, the pace will be too fast for a
student who has not seen *any* of the ideas and methods.

- Modern Quantum Mechanics, Second Edition, by J. J. Sakurai and Jim J. Napolitano.

- There will be no class on Monday 2 April because some of our students will be taking the Ph.D. qualifying exam.
- I need to be away on 28 May, 30 May, and 1 June. I will be at a workshop at DESY laboratory in Hamburg.
- We will have makeup classes at 17:00 on Fridays: 20 April, 27 April, and 4 May.

- 2 - 6 April. Sakurai, Chapter 7, sections 7.1 - 7.3. This is about the treatment of identical particles in quantum mechanics. We will return to other sections of chapter 7 later in the quarter.
- 9 - 13 April. Sakurai, Chapter 5, sections 5.1 - 5.2. Notes
*Perturbation theory for energy levels*sections 1 and 2. - 16 - 20 April. Sakurai, Chapter 5, sections 5.3 - 5.4. Notes
*The van der Waals interaction*. - 23 - 27 April. Sakurai, Chapter 5, section 5.5, the fist three subsections of section 5.6, and the first three subsections of 5.7. Notes
*Perturbation theory for energy levels*sections 3 - 5. Notes*The adiabatic approximation and Berry's phase*. - 30 April - 4 May. Sakurai, Chapter 5, section 5.7. Notes
*Time dependent perturbation theory*sections 1 - 6. - 7 - 11 May. Sakurai, Chapter 5, sections 5.8 - 5.9. Notes
*Time dependent perturbation theory*sections 7 - 13. - 14 - 18 May. Sakurai, Chapter 6, sections 6.1 - 6.3. Notes
*Scattering theory*sections 1 - 9. - 21 - 25 May. Sakurai, Chapter 6, sections 6.4 and 6.6. Notes
*Scattering theory*sections 10 - 13 and 15. - 28 May - 1 June. I will be at DESY laboraaory in Hamburg. No class.
- 4 - 8 June. Sakurai, Chapter 6, section 6.7. Notes
*Scattering theory*sections 16 - 18. You may want to look at the exam from last year.

- Wednesday 11 April: Sakurai, problems 7.2, 7.3, 7.5, 7.6. For problem 7.3, we suppose that the spatial wave functions are the same for both of the particles. For problem 7.6, you can ignore the question "What is the total spin in each case."
- Wednesday 18 April: Sakurai, problems 5.1, 5.2, 5.3, 5.4. (See solutions for problems 5.2, 5.3 and 5.4.)
- Wednesday 25 April: Sakurai, problems 5.12, 5.20, 5.21. (See solution for problem 5.12.)
- Wednesday 2 May: Sakurai, problems 5.22, 5.26, 5.30(a). Our midterm exam is also on 2 May. You may want to look at the midterm exam from last year. (See solution for problem 5.22.)
- Wednesday 9 May: Sakurai, problems 5.35 and 5.38. (See solution for problem 5.38.)
- Wednesday 16 May: Notes,
*Time dependent perturbation theory*, exercise 12.1. (See solution.) - Wednesday 23 May: Notes,
*Scattering theory*, exercise 6.1. - Wednesday 30 May: Notes, Sakurai problems 6.1 and 6.2. (Submit to Chris Newby.)
- Wednesday 6 June: Notes,
*Scattering theory*, exercises 15.1 and 15.2.

Exams are to be taken without notes or books. That is because I want to encourage you to remember the most important formulas for quantum mechanics. If you will need an obscure complicated formula for an exam question, I will give it on the exam.

Note: I encourage students to work together on the homework. I don't want you to just copy from someone else's work because you won't learn anything that way, but if you work out the solution jointly with someone else or with a group, that's fine. Real science usually involves teamwork, so it's a good idea for you to learn how to work on science with others. This policy is an exception to the normal university rule about doing your own work. Of course, on exams, your paper has to be entirely your own work.
