    I Extended hamiltonian operator for the Hydrogen atom

    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 Extended hamiltonian operator for the Hydrogen atom

    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...

    I Graviton Scattering: Compute Amplitudes w/Einstein Gravity

    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.
