The LSD on-top correlation hole n ¯ LSD (r, r) is not exact [63] (except in the high-density, lowc density, fully spin-polarized, or slowly-varying limit), but it is often quite realistic [64]. 85), its cusp is then also realistic. 182) can be very physical. 182) “unweights” regions of space where LSD is expected to be least reliable, such as near a nucleus or in the evanescent tail of the electron density [65,64].
