Question: Heisenberg picture spin precession ([1] pr. 2.1)
For the spin Hamiltonian
\begin{equation}\label{eqn:heisenbergSpinPrecession:20} H = -\frac{e B}{m c} S_z = \omega S_z, \end{equation}
express and solve the Heisenberg equations of motion for \( S_x(t), S_y(t) \), and \( S_z(t) \).
Answer
The equations of motion are of the form
