  • Theory of impurity-concentration dependence of freezing temperatures of metallic spin glasses 

    Shegelski, M. R. A., and D. J. W. Geldart. 1992. "Theory of impurity-concentration dependence of freezing temperatures of metallic spin glasses." Physical Review B (Condensed Matter) 46(5): 2853-63. Copyright © 1992 American Physical Society.
    The authors present a theory of the freezing temperature Tg of metallic spin glasses. Length scales associated with intrinsic sd scattering and finite temperature play essential roles. They describe an approach in which ...

  • Two-component scaling near the metal-insulator bifurcation in two dimensions 

    Geldart, D. J. W., and D. Neilson. 2003. "Two-component scaling near the metal-insulator bifurcation in two dimensions." Physical Review B (Condensed Matter and Materials Physics) 67(20): 205309-1. Copyright © 2003 American Physical Society.
    We consider a two-component scaling picture for the resistivity of two-dimensional (2D) weakly disordered interacting electron systems at low temperature with the aim of describing both the vicinity of the bifurcation and ...

  • Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals 

    MacDonald, A. H., R. Taylor, and D. J. W. Geldart. 1981. "Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals." Physical Review B (Condensed Matter) 23(6): 2718-30. Copyright © 1981 American Physical Society.
    The Umklapp fraction, , for electron-electron scattering in the alkali metals has been calculated using first-principles pseudopotentials. Both Coulomb scattering and phonon-exchange scattering have been included. For a ...

  • Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry 

    Kyriakidis, J., and D. J. W. Geldart. 1996. "Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry." Physical Review B (Condensed Matter) 53(17): 11572-81. Copyright © 1996 American Physical Society.
    Critical exponents and amplitude ratios for corrections to the scaling limit are calculated for a randomly diluted, weakly inhomogeneous O(m) Heisenberg model in an expansion in =4-d. Calculations for the exponents and ...

  • Wave-vector analysis of metallic surface energy 

    Rasolt, M., G. Malmstrom, and D. J. W. Geldart. 1979. "Wave-vector analysis of metallic surface energy." Physical Review B (Condensed Matter) 20(8): 3012-19. Copyright © 1979 American Physical Society.
    The exchange and correlation energy of a nonuniform electronic system can be decomposed into contributions of different wave-vector fluctuations. Both the long- and short-wavelength contributions to this energy can be ...

  • Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy 

    Rasolt, M., and D. J. W. Geldart. 1980. "Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy." Physical Review B (Condensed Matter) 21(8): 3158-66. Copyright © 1980 American Physical Society.
    The authors decompose the lowest-order nonlocal corrections to the local-density approximation to the exchange and correlation component of the metallic surface energy in terms its wave-vector components. Comparison with ...
