  1. Yang, W, Integral Formulation of Density-Functional Theory, edited by Samuel B. Trickey, Advances in Quantum Chemistry, vol. 21 no. C (1990), pp. 293-302(Invited paper.) [doi] .

    The Hohenberg-Kohn-Sham density-functional theory is reformulated in terms of explicit relations between the electron density and the effective potential through the use of Feynman path integrals. In this formulation electron density is the only basic variable as in the Thomas-Fermi theory and orbitals are not needed. Possible applications to calculations in large molecules and the present limitations of the method are discussed. © 1990 Academic Press, Inc.
