Q: [1] pr 4.12
Solve the spin 1 Hamiltonian \begin{equation}\label{eqn:crystalSpinHamiltonianTimeReversal:20} H = A S_z^2 + B(S_x^2 – S_y^2). \end{equation}
Is this Hamiltonian invariant under time reversal?
How do the eigenkets change under time reversal?
A:
In spinMatrices.nb the matrix representation of the Hamiltonian is found to be \be…
