一个模型系统中实际位势的Penrose匹配规则

Penrose Matching Rules from Realistic Potentials in a Model System

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

摘要:

我们展示了一个玩具模型的二元十次Al-Co准晶-密切相关的实际结构-其中现实的对势产生的基态,似乎完美地实现彭罗斯的匹配规则,HBS上的船星(HBS)瓷砖的边缘2.45 A。势的第二个最小值对这个结果至关重要。

英文摘要:

We exhibit a toy model of a binary decagonal Al-Co quasicrystal -- closely related to actual structures -- in which realistic pair potentials yield a ground state which appears to perfectly implement Penrose's matching rules, for Hexagon-Boat-Star (HBS) tiles of edge 2.45 A. The second minimum of the potentials is crucial for this result.
