Chapter 10:
Intro to Group Theory Chapter 11:
Young Diagrams and SU(N) Representations Grading
Scores on
quizzes, HW assignments and the MidTerm Exam can be seen on the Catalyst
gradebook. Postmidterm the column labeled Projected Score is
calculated assuming that the average (percentage) scores on the remaining HW
assignments are identical to those on the previous assignments and that the
(percentage) grade on the Final Exam is identical to that on the MidTerm Exam. The Projected Grade is a “flat”
(i.e., not highly curved) mapping of the scores onto the range 0.0 to 4.0
such that the highest score yields a 4.0 grade and that passing (a grade of
2.0) comes from a score of approximately 40%. This is just an estimate
of the Final Grade. The total score
and the grading algorithm will “mature” as more information becomes
available. It is to everyone’s advantage to learn from the HW sets and
do well on the Exams and quizzes. Prerequisites
– successful completion of Phys 1213, 225 (Quantum I) and 227 (Elementary
Mathematical Physics I); Phys 228 is
recommended. We will briefly discuss the most relevant subjects from Phys.
227 and 225 in Lectures 1 and 5.
Students are also encouraged to review the content of all of Phys. 227
in the Lecture Notes from the last time I taught that course (2008), which
are available here. It is
expected that students entering Phys 226 have some working knowledge of
special relativity and quantum mechanics.
Some facility with the following is assumed: complex variables and
complex arithmetic, harmonic (sines & cosines) and hyperbolic (sinh & cosh) functions,
simple transformations represented by matrices operating on vectors or state
vectors (including bras and kets), quantum numbers, eigenvalues and
eigenstates (in the context of quantum mechanics), quantized spin in simple
systems (e.g., spin ½ or related 2state systems), symmetries and conserved
quantum numbers. Textbooks
The course notes are the primary reference
for this class, but these books may also be useful: Reading Assignments
Please read prior to the
indicated week: (Note Tuesday, November 11 and Friday, November 28 are UW
holidays)
