The Classical-map Hyper-Netted-Chain (CHNC) technique for inhomogeneous electron systems. Application to quantum dots

The Classical-map Hyper-Netted-Chain (CHNC) technique is a simple method of calculating quantum pair-distribution functions, spin-dependent energies, etc., of strongly interacting uniform systems. We present CHNC calculations of charge densities and energies of non-uniform systems, viz., quantum dots, and compare with quantum Monte Carlo and density-functional results. Results for up to 210 electrons are reported.
