    Analytical expressions for the local-field corrections in double-layer electron systems
    (Academic Press, 1999) Tanatar, Bilal
    We develop an extension of the sum-rule version of the Singwi, Tosi, Land, and Sjolander (STLS) scheme applied to a double-layer electron system. We present analytical expressions for the intralayer and interlayer static structure factors and corresponding local-field corrections which agree quite well with the full STLS calculations. Some applications of our basic results and further generalizations of our method are discussed.

    Plasmon dispersion and damping in double-layer electron systems
    (Elsevier Science Ltd, Exeter, United Kingdom, 2000) Davoudi, B.; Tanatar, Bilal
    We use dynamical local-field corrections to study the plasmon dispersion and damping in double-layer electron systems. The wave vector and frequency-dependent local-fields describing the exchange-correlation effects are obtained within the quantum version of self-consistent field approach. The calculated plasmon dispersions are modified by the dynamic local-fields at intermediate wave vectors (i.e. q to approximately kF). The plasmons are damped outside the single-particle excitation region.
