Yes.. I wrote the post in a rush and so I didn't check it

Yes, this part it's a bit confused eheh! I meant that it is not hard at all to take into account also the spin coupling. In effect I have rewritten it in a totally different way!
Can I ask you another favor? I have modified a part of the text, if you have time can you please check it too? Thank you very much!
The evolution at time ∆t can be obtained multiplying the wave function at the initial time in the coordinate representation by the first of the two factors with which the time evolution operator has been represented. By a Fourier transform, the wave function is then written in the momentum representation and it is multiplied by the second factor of the time evolution, diagonal in that space. The inverse Fourier transform allows us to write the wave function back in the coordinate space and from there the procedure is repeated.
