Landau energy spectrum and quantum oscillator model for twisted   N-enlarged Newton-Hooke space-time
  We derive the energy levels for oscillator model defined on the twisted N-enlarged Newton-Hooke space-time, i.e., we find time-dependent eigenvalues and corresponding time-dependent eigenstates. We also demonstrate that for a particular choice of deformation parameters of phase space the above spectrum can be identified with the time-dependent Landau one.
