Hartree-Fock vs density of charge

  1. Nov 7, 2008 #1
    Hi all,

    If density of electron is high, Hartree-Fock approximation will work well under what conditions?
    What if the density is low?

    If the density is low, then HF is not good and correlation needs to be accounted for. For very low electron densities the electrons might from a Wigner crystal.
