Spin correlations in the low-density electron system
(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 ...
Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
(1986-11/15)
The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ...
Small and large wavelength contributions to the exchange and correlation energy of a nonuniform electron gas
(1982-04/15)
For the uniform electron gas, the decomposition of the exchange and correlation energy into its individual wave vectors has proved invaluable for both a deeper understanding of its structure as well as its extensions to ...
