Semiclassical Origins of Density Functionals
... Important features of these results include: (i) exact when v 0, where kF N 1=2=L; (ii) highly nonlocal functionals of the potential through F , which is set globally; (iii) TF theory retains only the first terms, and EF differs because of this; (iv) even if low-lying orbitals have turning ...
