Item Open Access Quasi-particle properties in a quasi-two-dimensional electron liquid(Indian Academy of Sciences, 2008) Asgari, R.; Tanatar, BilalWe consider the quasi-particle properties such as the effective mass and spin susceptibility of quasi-two-dimensional electron systems. The finite quantum well width effects are incorporated into the local-field factors that describe the charge and spin correlations. We employ the Fermi-hypernetted chain formalism in conjunction with fluctuation-dissipation theorem to obtain the local-field factors. Our results are in good agreement with recent experiments.Item Open Access Spin correlations in electron liquids: Analytical results for the local-field correction in two and three dimensions(Springer, 1998) Tanatar, Bilal; Mutluay, N.We study the spin correlations in two- and three-dimensional electron liquids within the sum-rule version of the self-consistent field approach of Singwi, Tosi, Land, and Sjölander. Analytic expressions for the spin-antisymmetric static structure factor and the corresponding local-field correction are obtained with density dependent coefficients. We calculate the spin-dependent pair-correlation functions, paramagnon dispersion, and static spin-response function within the present model, and discuss the spin-density wave instabilities in double-layer electron systems.
