Upper bounds of spin-density wave energies in the homogeneous electron gas
Upper bounds of spin-density wave energies in the homogeneous electron gas
Studying the jellium model in the Hartree-Fock approximation, Overhauser has shown that spin-density waves (SDWs) can lower the energy of the Fermi gas, but it is still unknown whether these SDWs are actually relevant for the phase diagram. In this paper, we give a more complete description of SDW states. …
