  • Plasmons in disordered, two-component, quasi-two-dimensional electron systems 

    Shegelski, M. R. A., and D. J. W. Geldart. 1989. "Plasmons in disordered, two-component, quasi-two-dimensional electron systems." Physical Review B (Condensed Matter) 40(6): 3647-51. Copyright © 1989 American Physical Society.
    The authors investigate the effect of elastic scattering of electrons on the properties of plasmons in a disordered, two-component, quasi-two-dimensional electron gas. Numerical results are given for dispersion relations ...

  • 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 ...
