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

    Gumbs, G.; Geldart, D. J. W. (1984-05/15)
    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.; Rosolt, M.; Geldart, D. J. W. (1988-02/15)
    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.; Neilson, D.; Swierkowski, L.; Szymanski, J.; Geldart, D. J. W. (1993-02/15)
    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 ...
