Physics 137B, Fall 2007 Quantum Mechanics II Midterm II review sheet The second midterm will be Thursday, Nov. 15, 9:30-11:00 a.m. No books, notes, or calculators are allowed, but the equations given below will also be given on the exam sheet. This should not be regarded as a complete list of everything we’ve covered in lecture. The equations mentioned below will be provided (without words) on the test sheet. Although you do not need to memorize them, you should know what they mean and how to use them. The second midterm will focus on all the material covered in lecture since the first midterm, but since much of this builds on earlier material, some knowledge from earlier in the course will be required. Time-dependent perturbation theory: we expand over unperturbed eigenstates ψ ( t ) = X k c k ( t ) exp( - iE (0) k t/ ¯ h ) ψ (0) k . (1) For a system in state a at t = 0, the coefficient of state b 6 = a is c (1) b ( t ) = ( i ¯ h ) - 1 Z t 0 dt H 0 ba ( t 0 ) e ba . (2)
