Problem Set Solutions
Welcome to the home page of QM I. 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 first quarter of our three part sequence on QM, you will study the basic equations, discussed the similarities and differences between the classical and QM descriptions, and solve some simple, typically one-dimensional problems. In the second quarter, 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 perturbation theory. In the final quarter, we'll delve into more advanced topics include the variational principle, WKB approximation, scattering theory, and a deeper look at the interpretation of QM.
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.
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.
Food: Our class meetings are at lunchtime and everyone has to eat sooner or later. So, if you must bring your lunch, you may do so, provided that you can still take notes while eating it and the smell is not unbearable (or so tasty that I'm tempted to steal it - triathletes are always hungry).
Plagiarism: Use your own very large brain (you're a physicist!) and don't even think about cheating. See homework rules below.
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).
You must give the full citation of any outside source that you employ in your solutions. Use of solutions to these problems from previous years or from other outside sources (including web pages that you find by googling for solutions to Griffiths) constitutes plagiarism and may result in failure (of the course).

The final exam will be on Tuesday, December 10, 10:30-12:30, in CAT 268.
Both exams will be half closed and half open book. "Open book" means that you may consult your own notes, your own homework, solutions and handouts that I have provided, and the assigned textbook.
