Momentum space quantum similarity measures versus moments of momentum Universiteit Gent
The experimentally obtainable moments of momentum have become a standard way to evaluate the performance of computational methods in p-space. The absolute percentage errors on the moments APE() with respect to those of a high quality electron momentum distribution (EMD), were previously studied by Hart and Thakkar1 and lead to the conclusion that DFT generally performs worse than Hartree-Fock (HF) in momentum space. These findings are ...
