这一补助金，在理论和计算化学 计划，支持理论研究，研究动态 以及分子和固体在低温下的弛豫。 激子的弛豫问题， 无序系统，以及强耦合到一个 恒温水库隧道将解决。 这部作品的意义在于它的基本见解 晶体材料的结构和性质， 它们与各种频率或颜色的光的相互作用。 这些见解将扩展到包括玻璃状固体， 它们不具有在以下中发现的规则排列的程度： 晶体 这些物质吸收能量的方式 材料是该项目的一个特别重点。 结果 将直接价值的团体进行实验， 这些材料。

This grant, in the Theoretical and Computational Chemistry Program, supports theoretical research to study the dynamics and relaxation of molecules and solids at low temperatures. Problems in relaxation of excitons, excitation transport in disordered systems, and the effect of strong coupling to a constant temperature reservoir on tunneling will be addressed. The significance of the work lies in the fundamental insights into the structure and properties of crystalline materials and their interactions with light of various frequencies or colors. These insights will be extended to include glassy solids, which do not have the degree of regular arrangement found in crystals. The ways in which energy is absorbed by these materials is a particular focus of this project. The results will be of direct value to groups performing experiments on these materials.
