The '''classical-map hypernetted-chain method''' ('''CHNC method''') is a method used in [[many-body problem|many-body]] [[theoretical physics]] for interacting uniform electron liquids in two and three dimensions, and for non-ideal [[plasma_(physics)|plasma]]s. The method extends the famous [[Hypernetted-chain equation|hypernetted-chain method]] (HNC) introduced by [[J. M. J. van Leeuwen]] et al.<ref>

Comparison of the calculated ''g''(''r'') with results from Quantum Monte Carlo show remarkable agreement, even for very strongly correlated systems.

The interacting pair-distribution functions obtained from CHNC have been used to calculate the exchange-correlation energies, [[Landau parameter]]s of [[Fermi liquid]]s and other quantities of interest in many-body physics and [[density functional theory]], as well as in the theory of hot plasmas .<ref>M.
