- W2000657713 abstract "The dynamic transverse spin susceptibility ${ensuremath{chi}}_{+ensuremath{-}}$ of a tight-binding Hubbard model of an itinerant-electron ferromagnet must exhibit a zero-frequency spin-wave mode if the starting Hamiltonian is spin-rotationally invariant. We give an explicit proof that ${ensuremath{chi}}_{+ensuremath{-}}$ for a semi-infinite Hubbard model will indeed have such a Goldstone mode if it is computed with the self-consistent-field approximation. We also derive a necessary and sufficient condition on the free-particle susceptibility ${ensuremath{chi}}_{+ensuremath{-}}^{0}$ which ensures that ${ensuremath{chi}}_{+ensuremath{-}}$ computed in this approximation will be spin-rotational invariant. Our work complements the more formal results of Brandt and co-workers on conserving approximations. We use our sum rule for ${ensuremath{chi}}_{+ensuremath{-}}^{0}$ to discuss various simplified models which have been used to describe the effect of a planar surface in Hubbard models. In particular, the work of Mathon is discussed." @default.
