Doye, J.P.K. and Wales, D.J.: The structure and stability of atomic liquids: From clusters to bulk, Science 271:484–487, 1996.

The report dealt with the factors that determined whether a substance will be a liquid or gas at a given temperature or pressure. The models adopted involved 55–256 atoms, and included interparticle forces whose values were set using an adjustable parameter. Potential energies were calculated, and the results showed that the model liquid became a model gas when interatomic forces became weaker. Reasoning in a manner similar to that in the first report, the authors argued that they had provided an explanation for phase transitions that occur in real systems.
