HW 1, due Thursday, Feb. 4

Reading: Sakurai, Sec. 4.4 (skim, don't get bogged down); Schwabl, Sec. 11.1.1
Problems: Sakurai Ch. 4, Problems 2, 3, 7, 11, 12.

Note: It is helpful NOT to use Dirac notation when dealing with anti-unitary operators. A unitary op U satisfies (Uv,Uw)=(v,w), where v and w are vectors in Hilbert space and (v,w) is the inner product. An anti-unitary operator Ω, such as the time-reversal operator, instead satisfies (Ωv,Ωw)=(v,w)* =(w,v).

Hint: For problem 7, I suggest that you begin by explaining why, under the assumptions of the problem, (v,Lv)=(Ωv,LΩv). (Here I've used Ω for the time-reversal operator since I don't have a capital Theta on my keyboard.)
