Spin polarization due to exchange? Would spin polarized ground state exist if no $e$-$e$ repulsion?
Non-relativistic no-magnetic-field many electron hamiltonian contains no spin operators. How would spin polarization happen in many electron ground state (modeled by LSDA DFT for instance)?
I often ...
