在水的最小Mercedes-Benz模式中冰的多形性

Ice polyamorphism in the minimal Mercedes-Benz model of water

Julyan H. E. Cartwright, Oreste Piro, Pedro A. Sánchez, Tomás Sintes

摘要:

我们调查冰多形的背景下的二维梅赛德斯-奔驰模型的水。我们发现一个一级相变之间的结晶相和高密度的非晶相。此外,我们发现高密度和低密度的两种非晶结构之间的可逆转变;然而,我们发现这是一个连续的,而不是突然的转变,因为低密度的非晶相不显示结构稳定性。我们讨论了这种行为的起源及其影响方面的最小通用建模的多晶。

英文摘要:

We investigate ice polyamorphism in the context of the two-dimensional Mercedes-Benz model of water. We find a first-order phase transition between a crystalline phase and a high-density amorphous phase. Furthermore we find a reversible transformation between two amorphous structures of high and low density; however we find this to be a continuous and not an abrupt transition, as the low-density amorphous phase does not show structural stability. We discuss the origin of this behavior and its implications with regard to the minimal generic modeling of polyamorphism.
