Abstract: We used the Hartree-Fock approximation to classify the electronic phases that might occur in a transition-metal nanowire. The important features of this situation are orbital degeneracy (or near degeneracy) and interactions favoring locally high-spin configurations. In this circumstance, spin density waves and triplet superconductivity are favored. If the interactions favor locally low-spin configurations as in previously studied spin-ladder systems, charge density waves, and singlet superconductivity are observed.
