Unless otherwise noted, these problems appear in my draft textbook
The Physics of Quantum Mechanics.
Assignment 1: (Due Wednesday, 13 September.)
- There are quite a few problems in this assignment, but each one is pretty short.
- Problem 3.11: The trace
- Problem 3.12: The outer product
- Problem 1.2: Exit probabilities
- Problem 1.5: Tilted analyzer loop
- Problem 1.6: Three analyzer loops
- Problem 1.7: Bomb-testing interferometer
Model Solutions 1:
Assignment 2: (Due Wednesday, 20 September.)
- Problems 3.1 through 3.4, inclusive: Photon polarization
- Problem 3.13: Pauli matrix algebra
Model Solutions 2:
Assignment 3: (Due Friday, 29 September.)
- You may want to read pages 1 through 70 of Daniel T. Gillespie,
A Quantum Mechanics Primer, at
this link.
Caution: Gillespie treats only systems with an infinite number
of basis states, he does not distinguish between a state |ψ> and
its representation ψ(x), and he uses the notation (φ,ψ)
for what Dirac would call <φ|ψ>.
