Wave-vector analysis of metallic surface energy
(1979-10/15)
The exchange and correlation energy of a nonuniform electronic system can be decomposed into contributions of different wave-vector fluctuations. Both the long- and short-wavelength contributions to this energy can be ...
Exchange and correlation energy in a nonuniform fermion fluid
(1986-07/15)
Recent results for the surface energy of jelliumlike surfaces are investigated within the functional-density formalism. These results along with first-principles considerations support the contention that the first gradient ...
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 ...
Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy
(1980-04/15)
The authors decompose the lowest-order nonlocal corrections to the local-density approximation to the exchange and correlation component of the metallic surface energy in terms its wave-vector components. Comparison with ...
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. ...
