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 ...
Adsorbate densities and surface potentials of physisorbed systems: A density-functional approach
(1987-06/15)
A density-functional approach for the calculation of the density of particles adsorbed on the surface of a solid is explored including the adparticle two-body interaction. The coverages and effective surface potentials so ...
Comment on `Quantum-mechanical interpretation of the exchange-correlation potential of Kohn-Sham density-functional theory'
(1990-07/09)
For original paper see M.K. Harbola and V. Sahni, ibid., vol.62, p.489 (1989). Harbola and Sahni suggested a procedure for constructing the exchange-correlation potential that enters the Kohn-Sham single-particle equations. ...
