  • Depth-dependent static shielding of an impurity by a quantum plasma in a magnetic field 

    Gumbs, G., and D. J. W. Geldart. 1984. "Depth-dependent static shielding of an impurity by a quantum plasma in a magnetic field." Physical Review B (Condensed Matter) 29(10): 5445-57. Copyright © 1984 American Physical Society.
    The static shielding of a charged impurity embedded in a quantum plasma is studied with the use of linear-response theory. The required response function is calculated in the random-phase approximation with a uniform ...

  • Diamagnetic susceptibility of a dense electron gas 

    Vignale, G., M. Rosolt, and D. J. W. Geldart. 1988. "Diamagnetic susceptibility of a dense electron gas." Physical Review B (Condensed Matter) 37(5): 2502-7. Copyright © 1988 American Physical Society.
    The authors calculate the diamagnetic susceptibility of a uniform interacting electron gas in the random-phase approximation. From this the exact high-density expansion of the diamagnetic susceptibility is obtained

  • Spin correlations in the low-density electron system 

    Green, F., D. Neilson, L. Swierkowski, J. Szymanski, et al. 1993. "Spin correlations in the low-density electron system." Physical Review B (Condensed Matter) 47(8): 4187-92. Copyright © 1993 American Physical Society.
    The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
