稳定蜂窝、正方形、简单立方和金刚石晶格的各向同性相互作用的非线性和设计

Dimensionality and design of isotropic interactions that stabilize honeycomb, square, simple cubic, and diamond lattices

摘要:

我们使用统计力学和计算机模拟的逆方法来研究是否各向同性的相互作用,旨在稳定一个给定的二维(2D)晶格也将有利于一个类似的三维(3D)结构,反之亦然。具体来说,我们确定的三维有序晶格有利于各向同性潜力优化,表现出稳定的二维蜂窝(或正方形)周期性结构,以及二维有序结构有利于各向同性相互作用,旨在稳定三维金刚石(或简单立方)晶格。我们发现一个显着的“可转移性”的各向同性电位设计,以稳定类似的形态在2D和3D,无论确切的相互作用形式,我们讨论了这种跨维行为的基础。我们的研究结果表明,发现驱动组装成某些感兴趣的3D周期性结构的相互作用可以通过针对类似的2D晶格的计算密集型优化来辅助。

英文摘要:

We use inverse methods of statistical mechanics and computer simulations to investigate whether an isotropic interaction designed to stabilize a given two-dimensional (2D) lattice will also favor an analogous three-dimensional (3D) structure, and vice versa. Specifically, we determine the 3D ordered lattices favored by isotropic potentials optimized to exhibit stable 2D honeycomb (or square) periodic structures, as well as the 2D ordered structures favored by isotropic interactions designed to stabilize 3D diamond (or simple cubic) lattices. We find a remarkable `transferability' of isotropic potentials designed to stabilize analogous morphologies in 2D and 3D, irrespective of the exact interaction form, and we discuss the basis of this cross-dimensional behavior. Our results suggest that the discovery of interactions that drive assembly into certain 3D periodic structures of interest can be assisted by less computationally intensive optimizations targeting the analogous 2D lattices.
