General course information

Course content: This is the first semester of a  graduate quantum mechanics course.
 
Textbook: There is no required textbook for the course, however all students should have at least one standard graduate quantum text on hand. A selection of recommended books is described below.

Reserve books: The books by Baym, Cohen-Tannoudji et. al.,  Landau & Lifshitz,  Sakurai, and Schwabl are (I hope) on reserve at EPSL.
 
Web pages: Homework assignments and supplementary material at www.glue.umd.edu/~tajac/622c/, homework grades and solutions at http://www.glue.umd.edu/~hsgoh/.

E-mail: I encourage students to make use of e-mail for quick correspondence with me regarding lecture material, homework problems, or whatever. I will also use e-mail to communicate with the class at large.

Homework: Assigned weekly and due the following week. Late homework accepted only under dire circumstances. If you know it will be impossible to turn in an assignment on time you must discuss this with me  in advance of the due date. The homework is an essential part of the course. I believe most of what you learn will come from doing the homework. You are encouraged to discuss the homework with others, but what you finally hand in should be your own work.  Sources (e.g. textbooks or classmates) should be cited when used heavily in a homework solution. Please make sure you include your name and the homework and course numbers and staple the pages together.

Exams: Two one-hour mid-terms and a final. The final is Thursday, Dec. 16, 10:30am-12:30pm.

Grading: REVISED: Based on homework (30%), one mid-term (30%), and final (40%),
with the best of  these raised by 20%  and the worst two lowered by 20%.
(Revised since it turned out the homework could all be graded. For the record, the old scheme
was: Based on homework (20%), two mid-terms (20% each), and final (40%), with the best two
of  these raised by 10% each and the worst two lowered by 10% each .)
The lowest two homework scores will be dropped. I cannot say for sure in advance, but I expect the letter grades to correspond to (roughly) (A) 100-80%, (B) 80-60%, (C) 60-40%.


Some texts
 

F. Schwabl,  Quantum Mechanics
Concise, well-organized, clear exposition.

C. Cohen-Tannoudji, B. Diu and F. Laloe, Quantum Mechanics
Massive, strong on both fundamentals and applications, excellent for self-study.

L.D. Landau and E.M. Lifschitz, Quantum Mechanics (Non-relativistic theory)
Practical and fundamental, with many applications and worked problems.

G. Baym, Lectures on Quantum Mechanics
Informal but sophisticated, very readable, with many applications.

J.J. Sakurai, Modern Quantum Mechanics
Written by a high-energy theorist, tilted toward the algebraic approach. Nice choice of examples.

L.I. Schiff, Quantum Mechanics
A ``standard" old-fashioned graduate textbook. Contains a lot of material and has a good table of contents.

E. Merzbacher, Quantum Mechanics
Another ``standard" graduate text, with the slant of a nuclear theorist. Strong on scattering theory.
A third edition came out in 1997.

H.A. Bethe and R. Jackiw, Intermediate Quantum Mechanics
Atomic structure, interaction with radiation, and scattering theory, beyond the usual introductory topics.

R. Shankar, Principles of Quantum Mechanics
Holds the student's hand, verbose, mostly elementary,  but has some very nice modern applications.

D.J. Griffiths, Introduction to Quantum Mechanics
A very well written modern undergraduate text,  neatly organized and lucid.

P.A.M. Dirac, Principles of Quantum Mechanics
An elegant classic.

R.P. Feynman, The Feynman Lectures on Physics, vol. III
A ``beginning undergraduate" text offering insights that keep professors coming back.

A. Messiah, Quantum Mechanics
Strong on the formal and mathematical aspects of the theory.

J. Preskill, Lecture Notes on Quantum Mechanics and Quantum Computation
Notes from a Cal. Tech. course. Includes a nice introduction to the fundamentals of QM.

M. Abramowitz and I. Stegun, Handbook of Mathematical Functions
Indispensable for special functions.

Gradshteyn and Ryzhik: Table of Integrals, Series, and Products
The best.
