• Nonuniqueness of the Potentials of Spin-Density-Functional Theory 

    Capelle, K.; Vignale, Giovanni, 1957- (American Physical Society, 2001)
    It is shown that, contrary to widely held beliefs, the potentials of spin-density-functional theory (SDFT) are not unique functionals of the spin densities. Explicit examples of distinct sets of potentials with the same ...
