Z1 and Z2 Clusters

The Z1 and Z2 potentials both have two maxima that resemble the Friedel oscillations that can occur for metal potentials. Like the Dzugutov potential they have a strong tendency for icosahedral and polytetrahedral order.

More information on the lowest-energy minima that we found for these two potentials can be accessed from the following pages:

Points files for each minimum are accessible from the Table. The work described on the above pages can be found in the following paper:
