    • Similar technique to split ab initio potentials was also discussed in, in which two schemes (fragment decomposition and range separation of the Coulomb operator) was suggested. Though their method is more or less subjected to the physical construction of the system, the arbitrary splitting proposed in Eq. (12) is much flexible. For example one can easily facilitate the sampling of the potential from quantum Monte Carlo (QMC) calculations on top of the DFT potential and simple model pair-potential as V=V~DFT+(VQMC-V~DFT) and V~DFT=VPP+(VDFT-VPP) using a three-layer scheme
