  "abstract": "For time-dependent systems the wavefunction depends explicitly on time and it is not a pure state of the Hamiltonian. We construct operators for which the above wavefunction is a pure state. The method is based on the introduction of conserved quantities $Q$ and the pure states are defined by ${\\hat Q}\\psi=q\\psi$. The conserved quantities are constructed using parametrised mechanics and the Noether theorem.",
