Query: Quantization of a one-dimensional time-dependent periodic system with
  Hamiltonian and constants of motion approaches   For a particle moving in a one-dimensional space an under a periodic external
force, its quantization is study using the Hamiltonian (generalized linear
momentum quantization) and constant of motion (velocity quantization)
approaches. it is shown a great difference on the quantization of both
approaches and the ambiguities arisen by using the quantization on the
constants of motion.
