几乎真实模型中Al-Co势的匹配规则

Matching rules from Al-Co potentials in an almost realistic model

Sejoon Lim, M. Mihalkovic, C. L. Henley

摘要:

我们认为一个模型十次准晶的组成Al $_{80.1}$ Co $_{19.9}$ -密切相关的实际结构,并使用现实的对势-准晶格的候选网站。根据模拟,它的基态是一个满足彭罗斯匹配规则的Hubrillon-Boat-Star平铺。在本说明中,我们合理化这些结果的潜力,铝钴第二邻居势阱是至关重要的。

英文摘要:

We consider a model decagonal quasicrystal of composition Al$_{80.1}$Co$_{19.9}$ -- closely related to actual structures, and using realistic pair potentials -- on a quasilattice of candidate sites. Its ground state, according to simulations, is a Hexagon-Boat-Star tiling satisfying Penrose's matching rules. In this note, we rationalize these results in terms of the potentials; the Al-Co second-neighbor potential well is crucial.
