'''CHNC''' is used as the acronym for a method in many-body theoretical physics known as the '''C'''lassical-'''M'''ap '''H'''yper-'''N'''etted-'''C'''hain technique. It has been applied to interacting uniform [[electron liquidsliquid]]s in two and three dimensions, and to interacting electron-proton[[hydrogen plasmas]].

In this method, the pair-distributions of the interacting particles are calculated using a mapping which ensures that the quantum mechanically correct non-interacting pair distribution functiom is recovered when the Coulomb interactions are switched off. The value of the method lies in its ability to calculate the ''interacting'' pair distribution functions ''g(r)'' at zero and finite temperatures. Comparison of the calculated ''g(r)'' with results from Quantum Monte Carlo show remarkable agreement, even for very strongly correlated systems.
