论文摘要
对深层冷冷液体的理论处理很困难，因为它们的特性来自自我诱导，短暂和纳米镜的空间不均匀性。我使用计算机模拟来分析接近实验玻璃转变的平衡系统中的自我诱导的静态和动态异质性。我表征了基本介质系统中显着动态和热力学特性的样本对样品的广泛波动。关于局部生命的结果和动态异质性的分布与最近的单分子研究非常吻合。还发现了出人意料的热力学波动，这与动力学波动良好相关，从而提供了对缓慢动力学的热力学起源的局部测试。
A theoretical treatment of deeply supercooled liquids is difficult because their properties emerge from spatial inhomogeneities that are self-induced, transient, and nanoscopic. I use computer simulations to analyse self-induced static and dynamic heterogeneity in equilibrium systems approaching the experimental glass transition. I characterise the broad sample-to-sample fluctuations of salient dynamic and thermodynamic properties in elementary mesoscopic systems. Findings regarding local lifetimes and distributions of dynamic heterogeneity are in excellent agreement with recent single molecule studies. Surprisingly broad thermodynamic fluctuations are also found, which correlate well with dynamics fluctuations, thus providing a local test of the thermodynamic origin of slow dynamics.
