In DFT, indicates that a functional of the density gradient (i.e., f[grad rho]) is included in addition to a local functional. The most popular NL exchange functional is that by Becke. Popular NL correlation functionals are those by Lee/Yang/Parr and by Perdew. A functional that includes nonlocal terms is sometimes called "gradient-corrected" or a "GGA," which stands for "generalized-gradient approximation."

Not depending upon space and time. A nonlocal effect occurs instantaneously and with no attenuation due to distance. Special Relativity seems to forbid all such non-local effects, but Bell's Theorem seems to show that quantum mechanics demands them. The only solution thus far offered to this contradiction are that nonlocal effects involve "consciousness" rather than energy (Walker, Herbert) or that they involve "information" rather than energy (Sarfatti).
