QM Lecture 14
Chapter-14 QUANTIZATION of ANGULAR MOMENTUM
CASE: Spin one (The Feynman Lectures on Physics Vol. III Ch. 5)
1. Summary transformation of coordinates
2. Apparatus to Measure the spin: The Stern-Gerlach Apparatus
The Modified Stern-Gerlach Apparatus
3. Experiments with spins
Experiments with two similar filters in succession: Amplitude Probability
Experiments with filtered atoms
Stern-Gerlach filters in series: Once filtered, atoms lack memory of their states in the past
4. Base states
5. The distinctive feature of quantum mechanics: the interference of the amplitude probabilities
Our Fundamental Quantum Law
6. Summary of important general laws about amplitudes
7. The machinery of quantum mechanics: How to describe the behavior of a complicated apparatus A
CASE: Spin one-half (The Feynman Lectures on Physics Vol. III Ch. 6)
1. Summary of Transformation of Coordinates
2. The Stern-Gerlach Apparatus
3. Selection of the spin-basis
Central question
The reference basis
The rotated basis
4. Calculation of the relationship between thebasis and the rotated basis for arbitrary rotations
Rotation around the z-axis
APPENDIX A. Transformation of coordinates under the rotation of the reference axes
