Phase separation in Hubbard model
The Hartree-Fock ground-state phase diagram of the one-dimensional Hubbard model is calculated in the mu-U plane, restricted to phases with no charge density modulation. This allows antiferromagnetism, saturated ferromagnetism, spiral spin density waves and a collinear structure with unit cell up ar...
