COURSE SYNOPSIS

Basic principles of nonrelativistic quantum theory and applications. Schroedinger theory, quantum theory of angular momentum, matrix mechanics, perturbation theory, identical particles, scattering.
PREREQS: PH 435/PH 535 and PH 451/PH 551 or equivalents.

EVALUATION OF STUDENT PERFORMANCE

Students' achievements will be evaluated based on three required activities:

1. Homework (25%) will be assigned nearly every week. Collaboration on homework exercises is encouraged provided proper attribution is given, but each student must write an independent presentation of the solution. Solutions to all assigned problems will be posted on the Web one week after they are assigned. To receive credit, work must be submitted before the solution is posted.

2. Midterm Examination (30%)  9:00-9:50am, 2-13-2009, Wngr 377

3. Final Examination (45%) 10:00am-noon, 3-17-2009, Wngr 377
