Books:
- Quantum Mechanics Using Maple : With 75 Exercises and Cross Platform
Diskette Containing 39 Guided Maple Sessions/Book and Disk by Marko Horbatsch.
(Springer Verlag ,1995) ISBN: 3540588752
- Quantum Mechanics Using Computer Algebra : Includes Sample Programs
for Reduce, Maple, Mathematica and C++ by Willi-Hans Steeb. (World Scientific
Publishing Co., 1994) ISBN: 9810217706
- The Picture Book of Quantum Mechanics by Siegmund Brandt and Hans Dieter
Dahmen. 2nd Edition (Springer Verlag ,1995) ISBN: 0387943803 . . . . .
. very good for ideas for graphs to aid visualization
- Introduction to Quantum Mechanics by David J. Griffiths. (Prentice
Hall, 1994) ISBN: 0131244051 This is a widely used upper-level undergraduate
text. It has relatively few graphs so it is especially open to help from
Maple.
- Quantum Mechanics (Physics and Its Applications) by David S. Betts
and Paul C.W. Davies. 2nd Edition (Chapman & Hall, 1994) ISBN: 0412579006
. . . only about 100 pages long.
- Understanding Quantum Mechanics , Morrison - Out of print?? . . . quite
excellent because of its good discussion of fundamental concepts.

Topics for which Maple should be especially useful:
- 1) Group velocity.
- 2) Shooting technique - a predictor technique for solving differential
equations. (predictor/corrector approach). Very good for determining eigenvalues
and eigenfunctions.
- 3) Visualization of electromagnetic waves to wave packets, matter waves
and their wave packets.
- 4) Operators and commutation relations.
- 5) Stern-Gerlach experiment - can have 3, 5, 7, etc., angular momentum
states.
- 6) Use "solve" to solve one dimensional problems like scattering
off a well, a finite well (square or other interesting shapes), Can quickly
do a finite square well in one class period. ( Pedagogical suggestion bring
worksheet in and go through it during class). For the harmonic oscillator
have Maple do the brute force and you do the elegant method with raising
and lowering operators.
- 7) Hydrogen atom and other central potentials such as Yukawa, Lennard-Jones,
Morse. Might want to compare the solutions for other central potentials
with the hydrogen atom. Also other three-dimensional potentials such as
the square well - it is actually r^n as n goes to infinity.
- 8) All the angular momentum "stuff". Use phi and theta equations
already derived and then have them plot them and see what they look like.
- 9) Perturbation techniques: time independent, degenerate and non-degenerate.
(Why do perturbation techniques when with Maple - do you really need it
for one-dimensional or even three dimensional problems? Must understand
the idea of perturbation theory - the concept of representing an arbitrary
function in terms of a set of orthogonal functions. )
- 10) Matrix formulation of QM - Maple wonderful for manipulation of
matrices. Even two-state problems can have quite tricky matrices.
- 11) Animation of the time-dependence of solutions; for example the
solutions to the coupled square well, or make an arbitrary localized state
and demonstrate what happens in time.
- 12) Classical probability density and quantum probability density approaching
each other. Need to use coherent states - the Rydburg atom and the harmonic
oscillator have potential.
Philosophy of Pedagogy:
- 1) GRAPH, GRAPH, GRAPH.
- 2) Model using Maple in the classroom as we use it as professionals.
Set up the problem and describe the physical situation using pencil and
paper turn to Maple to do the difficult and tedious computations.
- 3) Bring in overheads which show graphs (usually Maple) but then have
the students go "home", bring down the appropriate Maple worksheet
which show completely or incompletely how to do the problem. Their homework
is an extension of the problem or a variation.
- 4) What are some real problems and sources for them that would require
the use of Maple? There are some Russian problem books that might be good
resources. Quark confinement/alpha decay are two specific suggestions.
