The first postulate of quantum mechanics says that every physical system is associated with a separable complex Hilbert space, however this does not hold for a free particle, where the basis is uncountable (all the momentum kets). I think it also does not hold for a free falling particle (V=mgz), where the eigenfunctions are the Airy functions.
how is that?
Thanks
