Question:
Example 4.4, couched in terms of forces, was a quasi-classical explanation for the Stern–Gerlach effect. Starting from the Hamiltonian for a neutral, spin- 1/2 particle traveling through the magnetic field given by Equation 4.169,
use the generalized Ehrenfest theorem (Equation 3.73) to show that
Equation 4.170 is therefore a correct quantum-mechanical statement, with the understanding that the quantities refer to expectation values.
Example 4.4
