  • Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II 

    Geldart, D. J. W., and M. Rasolt. 1980. "Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II." Physical Review B (Condensed Matter) 22(8): 4079-80. Copyright © 1980 American Physical Society.
    For pt.I see ibid., vol.15, p.1523 (1977). It is shown that the nonanalytic structure of the wave-number-dependent susceptibility noted by Geldart and Rasolt is not removed by including repeated particle-particle scattering

  • Comment on `Exact electron-gas response functions at high density' 

    Rasolt, M., D. J. W. Geldart, D. C. Langreth, and S. H. Vosko. 1988. "Comment on `Exact electron-gas response functions at high density'." Physical Review Letters 60(19): 1983-4. Copyright © 1988 American Physical Society.
    For original paper see D.C. Langreth and S.H. Vosko, ibid., vol.59, p.497 (1987). Langreth and Vosko calculated correlation contributions to the Hohenberg-Kohn energy response function Kxc(q,k). They claimed that the results ...

  • Comment on `Quantum-mechanical interpretation of the exchange-correlation potential of Kohn-Sham density-functional theory' 

    Rasolt, M., D. J. W. Geldart, M. K. Harbola, and V. Sahni. 1990. "Comment on `Quantum-mechanical interpretation of the exchange-correlation potential of Kohn-Sham density-functional theory'." Physical Review Letters 65(2): 276-7. Copyright © 1990 American Physical Society.
    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. ...

  • Exchange and correlation energy in a nonuniform fermion fluid 

    Rasolt, M., and D. J. W. Geldart. 1986. "Exchange and correlation energy in a nonuniform fermion fluid." Physical Review B (Condensed Matter) 34(2): 1325-8. Copyright © 1986 American Physical Society.
    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 ...

  • Gradient corrections in the exchange and correlation energy of an inhomogeneous electron gas 

    Rasolt, M., and D. J. W. Geldart. 1975. "Gradient corrections in the exchange and correlation energy of an inhomogeneous electron gas." Physical Review Letters 35(18): 1234-7. Copyright © 1975 American Physical Society.
    A closed form expression for the coefficient Bxc which determines the first gradient corrections to the exchange and correction energy is derived. The exact expression is obtained from an approximation that includes the ...

  • Small and large wavelength contributions to the exchange and correlation energy of a nonuniform electron gas 

    Rasolt, M., and D. J. W. Geldart. 1982. "Small and large wavelength contributions to the exchange and correlation energy of a nonuniform electron gas." Physical Review B (Condensed Matter) 25(8): 5133-46. Copyright © 1982 American Physical Society.
    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 analysis of metallic surface energy 

    Rasolt, M., G. Malmstrom, and D. J. W. Geldart. 1979. "Wave-vector analysis of metallic surface energy." Physical Review B (Condensed Matter) 20(8): 3012-19. Copyright © 1979 American Physical Society.
    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 ...

  • Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy 

    Rasolt, M., and D. J. W. Geldart. 1980. "Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy." Physical Review B (Condensed Matter) 21(8): 3158-66. Copyright © 1980 American Physical Society.
    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 ...
