That is very interesting, and makes a lot of sense since the pauli equation seems to be the nonrelativistic limit of dirac equation. Thanks, I will definitely take a look on this group theory derivations.

I am familiar with the usual solution of the hydrogen atom using the associated legendre functions and spherical harmonics, but my question is: is it possible to extend the hamiltonian of the hydrogen atom to naturally encompass half integer spin? My guess is that spin only pops in naturally in...

Thank you!

Is it possible to compute scattering amplitudes of a graviton interaction taking Einstein gravity as an effective field theory at low energies? I did not study qft the proper way yet, so any clarifications on the subject would be welcome.
