Resumen:
The Hartree-Fock (HF) energies of a new set of HF orbitals with long-range order are calculated for two different models which involve a system of many fermions interacting via repulsive delta potentials as a preliminary step facing such problems as the electron gas system, 3He systems, etc., where, however, the calculation of the relevant matrix elements is considerably more difficult. The models considered illustrate paramagnetic and antiferromagnetic behaviour. The authors find a whole new set of HF orbitals which are more stable than the (trivial) plane wave orbitals as well as the classic Overhauser ones.
