question concerns a spin-particle in a magnetic field. The Hamiltonian matrix governing this system is Ĥ = −wŜy = ħw [0 2 where w is the Larmor frequency. (a) Use the generalized Ehrenfest theorem to obtain an expression for the rate of change of (S) in this system, expressing your answer in terms of w and (S₂). (b) Verify that the orthonormal spinors li ₂0 and y = Q are eigenvectors of Ĥ and give their eigenvalues.
