玻璃化转变和三维以上的无规密堆积

Glass transition and random close packing above three dimensions

Patrick Charbonneau, Atsushi Ikeda, Giorgio Parisi, Francesco Zamponi

摘要:

最近发现的静态和动态的玻璃理论之间的严重差异的动机,我们数值研究致密的硬球在空间维度3至12的行为。我们的结果是一致的静态副本理论,但不同意动态模式耦合理论,表明高维物理的关键成分从后者失踪。我们还获得了随机密堆积密度的数值估计,这为大尺寸堆积球的数学问题提供了新的见解。

英文摘要:

Motivated by a recently identified severe discrepancy between a static and a dynamic theory of glasses, we numerically investigate the behavior of dense hard spheres in spatial dimensions 3 to 12. Our results are consistent with the static replica theory, but disagree with the dynamic mode-coupling theory, indicating that key ingredients of high-dimensional physics are missing from the latter. We also obtain numerical estimates of the random close packing density, which provides new insights into the mathematical problem of packing spheres in large dimension.
