摘要翻译：
通过对硬球系统自由能泛函模型的数值最小化，我们发现，在玻璃态自由能最小值处，时均密度场的局部峰的宽度表现出很大的空间变化，类似于动力学非均匀性模拟中的“局部Debye-Waller因子”的变化。从玻璃态自由能极小值处密度分布产生的粒子构型出发的分子动力学模拟显示了类似的局域化程度的空间异质性，暗示了动力学异质性与玻璃态自由能极小值的结构之间的直接联系。

英文摘要：
From numerical minimization of a model free energy functional for a system of hard spheres, we show that the width of the local peaks of the time-averaged density field at a glassy free-energy minimum exhibits large spatial variation, similar to that of the ``local Debye-Waller factor'' in simulations of dynamical heterogeneity. Molecular dynamics simulations starting from a particle configuration generated from the density distribution at a glassy free-energy minimum show similar spatial heterogeneity in the degree of localization, implying a direct connection between dynamical heterogeneity and the structure of glassy free energy minima.
