Grzegorz Szamel of Colorado State University is supported by an award from the Theoretical and Computational Chemistry program to study the dynamics of quiescent and driven glassy fluids, using a combination of numerical simulation and formal statistical mechanics. The research is pursuing three goals: 1) to obtain explicit numerical predictions for the correlation length in quiescent glassy fluids; 2) to develop a new theory for the glass transition that goes beyond mode-coupling theory and 3) to develop a theory for the dynamics of fluctuations in driven glassy fluids. This work is contributing fundamental understanding of several phenomena, such as shear flow, that are important for materials processing leading to fewer defects and better performance.

科罗拉多州立大学的 Grzegorz Szamel 获得理论和计算化学项目奖项的支持，利用数值模拟和形式统计力学的结合来研究静态和驱动玻璃态流体的动力学。该研究追求三个目标：1）获得静态玻璃态流体中相关长度的明确数值预测； 2) 发展一种超越模式耦合理论的新玻璃化转变理论，3) 发展一种驱动玻璃态流体波动动力学的理论。这项工作有助于对剪切流等几种现象的基本理解，这些现象对于材料加工非常重要，可以减少缺陷并提高性能。
