This web site is the home page of QM II. This is your resource page for information about the course, including homework assignments, exams, and solutions. This web page is also the syllabus for the course. To save paper, I will not print and distribute copies of documents in class. You may read them on the web or your computer and print out if you need.

In this second quarter of our three part sequence on QM, we'll move on to three dimensional problems, and the QM description of the Hydrogen atom, from which you could first see how the QM formulation yields accurate predictions of the observed phenomena, and begin study of multi-particle systems and (if there's time) perturbation theory.

Here are the topics we'll cover in QM II

- Quantum Mechanics in Three Dimensions (Ch. 4)
- The Schroedinger Equation in Three Dimensions
- The Hydrogen Atom
- Angular Momentum
- Spin

- Identical Particles (Ch. 5)
- Two-Particle Systems
- Atoms
- Solids
- Quantum Statistical Mechanics

- Time-Independent Perturbation Theory (Ch. 6)
- Nondegenerate Perturbation Theory
- (maybe) Degenerate Perturbation Theory

- Solve for the eigenstates and energies of a single particle in three dimensions for the case of central potential.
- Understand the detailed structure of the wave function for Hydrogen and hydrogen-like atoms.
- Compute properties of systems including orbital angular momentum and spin, including magnetic moments.
- Solve for the eigenstates and energies of multiple particle systems such as occur in simple atoms and solids.
- Find most probable configurations and energies of many-particle, many-level systems using quantum statistical mechanics.
- Use knowledge of the eigenstates and energies of simple systems and approximation methods to solve for energies of perturbed systems.

See the course outline above for the chapters that correspond to the material covered in this course.

I will also hand out photocopies of selected passages from other QM texts, as necessary to supplement Griffiths.

Final Exam: 40%

Problem Sets: 30%

Midterm Exam: 25%

Class Participation: 5%

Electronic distractions: Silence your cell phone or leave it home. Only phone calls (to me) from the Nobel Prize committee will be tolerated. Laptop computers may be used only for taking notes. Web surfing, texting, reading/sending email is prohibited during class. I will ask you to leave the class if you violate this rule.

Plagiarism: Use your own very large brain (you're a physicist!) and don't even think about cheating. See homework rules below.
The usual University rules apply. By
stepping into the classroom, you agree to abide by Drexel's policy on
Academic Integrity

Students with disabilities requesting accomodation and services at Drexel University need to present a current accomodation letter (AVL) to faculty before accomodations can be made. This cannot be done retroactively. AVL's are issued by the Office of Disability Services (ODS). For additional information, contact ODS at www.drexel.edu/ods 3201 Arch St., Suite 210, 215-895-1401 (V), or 215-895-2299 (TTY).

There will be eight problem sets. You will have a week to a week and a half to complete each. No late homework will be accepted. Please neatly and accurately write up your solutions to these problems; the notation of QM is quite compact in places and small differences in the equations can have large differences in meaning. I will hand out solutions to the problems on or shortly after their due dates, to give you feedback as quickly as possible.

You may discuss the homework with your classmates, but you and you alone are responsible for the work that you turn in. Please write up your own solutions to the problems. Breaches of this policy will result in homework scores being divided by the number of ``participants.'' Second offenses may result in failure (of the class).

Use of solutions to these problems from previous years or any other source constitutes plagiarism. You must attribute (by giving the correct reference) any significant help that you receive from outside sources.

The midterm will be in class on Wednesday, February 14.

The final exam (Friday, March 23, 8:00-10:00am, Disque 108) will be roughly 1/3 from the first half of the course, 2/3 from the second half.

Both exams will be half closed and half open book (textbook, your notes, my handouts, your problem sets, my solutions).
