Bryn Mawr Physics 302- Advanced Quantum Mechanics - 2010
Assignment #2 (shortened somewhat)
Due: Friday, Feb. 5 at 10:00 am.
Reading: Chapter 2 of Townsend
1.9 For this problem, assume that the states are as given in equation (1.32); do not limit your proof to the more specific case of spin states (equation 1.5).’
2.6 (I suggest you wait until after class Tuesday to start this problem.)
2.19 (You can do part a of this now, but I suggest you wait until after class Tuesday to start part b of this problem.)
2A. For a situation described by equations (1.32) through (1.48), explain briefly why , where the right side is the identity operator. This relation is used very frequently.
2B. In your own words and equations, draw the analogies between equations (1.32), (1.34), and (1.37) and the equivalent equations for ordinary two-dimensional vectors. Support your discussion with at least two figures.
