Hypernetted-chain equation of state for the two-dimensional Lennard-Jones fluid

Abstract
Values of the radial distribution functions and thermodynamic properties for the two‐dimensional Lennard‐Jones fluid are obtained from the hypernetted‐chain (HNC) theory. Results are reported for a wide range of temperatures and densities and are compared with computer simulations and with our earlier Percus–Yevick (PY) values. The HNC radial distribution functions agree with the computer simulations better than do the PY results, but the PY theory yields more accurate thermodynamic properties.
