拟混沌斑块粒子系统的phase diagrams计算

Computing phase diagrams for a quasicrystal-forming patchy-particle system

Aleks Reinhardt, Flavio Romano, Jonathan P. K. Doye

摘要:

我们介绍了一种方法来计算准晶体的自由能,我们用它来计算系统的二维斑片状粒子与五个规则排列的补丁,以前已被证明形成十二方准晶的相图。我们发现,准晶是一个结晶稳定相的条件范围很广,仍然是一个强大的功能的系统作为潜在的参数变化。我们还表明,准晶体是熵稳定的晶体近似。

英文摘要:

We introduce an approach to computing the free energy of quasicrystals, which we use to calculate phase diagrams for systems of two-dimensional patchy particles with five regularly arranged patches that have previously been shown to form dodecagonal quasicrystals. We find that the quasicrystal is a thermodynamically stable phase for a wide range of conditions and remains a robust feature of the system as the potential's parameters are varied. We also demonstrate that the quasicrystal is entropically stabilised over its crystalline approximants.
