- Descripción
- For a degenerate electron gas confined to a half-space or a slab the spin polarization produced by a point field is calculated. For the half-space both in three and one dimensions the analytic solution contains the usual RKKY polarization around the source plus a polarization wave originating from the mirror point, however, with the same phase at the border; there both are cancelled by a third term. In the slab the integrated polarization is finite, while it vanishes for the finite line.
