Exchange and correlation energy in a nonuniform fermion fluid
Abstract
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 coefficient of the exchange and correlation energy, in its unmodified form, is the proper nonlocal correction to the local-density approximation in extended systems
