E. Lomba et al., Inhomogeneous integral equation approach to pair and triple correlations in a glass-forming simple liquid - art. no. 011203, PHYS REV E, 6301(1), 2001, pp. 1203
A simple model of glass-forming liquid modeled via Dzugutov's pair potentia
l is studied by means of the triplet hypernetted chain approximation as for
mulated by Attard [P. Attard, J. Chem. Phys. 93, 7301 (1990)]. This system,
which is known to be mostly dominated by microscopic icosahedral ordering,
eludes a correct description in terms of classical two-body integral equat
ion theories. However, it is found here that the simple hypernetted chain a
pproximation when applied at the three-particle level can yield a correct s
emiquantitative description of both the pair and tripler structure of the s
upercooled state, capturing features which escape mure sophisticated closur
es implemented on the two-particle level.
