各向异性势单组分液体玻璃化转变的统计力学

Statistical Mechanics of the Glass Transition in One-Component Liquids with Anisotropic Potential

Valery Ilyin, Edan Lerner, Ting-Shek Lo, Itamar Procaccia

摘要:

我们研究了最近引入的单组分玻璃形成液体的模型,其成分与各向异性势相互作用。该系统本身是有趣的,并且作为液体如甘油(通过氢键相互作用)的模型,甘油是优良的玻璃形成剂。我们计算出了这个系统的统计力学,使用适当的准粒子(其中36个)对液体和玻璃无序进行编码。该理论提供了一个完整的解释的玻璃化转变现象,包括确定一个发散的长度尺度和结构变化和发散的弛豫时间之间的关系。

英文摘要:

We study a recently introduced model of one-component glass-forming liquids whose constituents interact with anisotropic potential. This system is interesting per-se and as a model of liquids like glycerol (interacting via hydrogen bonds) which are excellent glass formers. We work out the statistical mechanics of this system, encoding the liquid and glass disorder using appropriate quasi-particles (36 of them). The theory provides a full explanation of the glass transition phenomenology, including the identification of a diverging length scale and a relation between the structural changes and the diverging relaxation times.
