WebFeb 22, 2016 · The Attempt at a Solution. A stationary state is any quantum state which consists of only one eigenstate of the Hamiltonian H. For example, if a spin 1/2 system in the z basis with a magnetic field in the z-direction, a stationary state we may work with is ψ (0)> = a +>. In the same system, a non-stationary state would be ψ (0)> = a +> + b ->.
