| Outline of Final Research Achievements |
We studied multi-component hard-sphere systems to understand the material-composition dependence of the glass formation mechanism. We remark on the densest packing state, which is independent of the process of preparation but determined only by the material composition. The densest state is realized in a computer by full search of the macroscopic states. For this aim, we developed the method by unifying the Wang-Landau sampling and the replica exchange method. It is found that the search is accelerated by employing macroscopic state variables in addition to the particle density. In high density region, we find the Wang-Landau sampling does not converge. We avoided it by the extrapolation and analyze the reason in detail.
