David Reichmann of Columbia University is supported by an award from the Theoretical and Computational Chemistry program to carry out research on the development of theoretical techniques for the study of supercooled liquids, glasses, and other soft materials. The PI and his group are studying the connection between structure and dynamics in supercooled liquids, developing theoretical approaches to calculate time correlation functions close to the glass transition, and undertaking the development of a precise exposition of the scaling properties of dynamical heterogeneity in supercooled liquids, and will study self-assembly in nanoparticle and colloidal systems. The work is having a broader impact on a number of different fields including materials science and biology.

哥伦比亚大学的David Reichmann得到了理论和计算化学计划的奖项的支持，该计划旨在进行研究，以开发用于研究超冷液体，眼镜和其他软材料的理论技术。 PI和他的小组正在研究超冷液体中的结构与动态之间的联系，开发了理论方法来计算接近玻璃过渡的时间相关函数，并开发了超冷液体中动力异质性缩放特性的精确阐述，并将研究纳米机构和胶体系统中的自组装。 这项工作对包括材料科学和生物学在内的许多不同领域产生了更大的影响。
