The Structure and Stability of Atomic Liquids: From Clusters to Bulk

New insights into the structure of simple liquids are gained by analysing the
effect of the range of the interatomic forces on the multidimensional
potential energy surfaces of bulk material and clusters.
A microscopic understanding is provided of how the liquid phase is destabilised
in systems with very short-ranged interparticle forces.
For small clusters bound by long-ranged interatomic forces
the lowest energy minimum has an amorphous structure typical of the liquid-like state.
This suggests an explanation for the transition from electronic to geometric magic numbers
observed in the mass spectra of sodium clusters.
