Mapping the magic numbers in binary Lennard-Jones clustersJonathan P. K. Doye and Lars MeyerPhys. Rev. Lett. 95, 063401 (2005)AbstractUsing a global optimization approach that directly searches for the composition of greatest stability, we have been able to find the particularly stable structures for binary Lennard-Jones clusters with up to 100 atoms for a range of Lennard-Jones parameters. In particular, we have shown that just having atoms of different size leads to a remarkable stabilization of polytetrahedral structures, including both polyicosahedral clusters and at larger sizes structures with disclination lines.The full paper is available from Physical Review Letters Online and arXiv.org.
