This grant supports theoretical research on the dynamics of physically adsorbed layers of atoms and molecules on solid surfaces. The goal is to achieve a quantitative understanding of the interaction of atoms and molecules with surfaces in examples where the adsorbate and substrate are weakly modified by the interactions. The work is a combination of analytically-based theory and computations which can be performed using work stations. The topics include the analysis of the normal modes (phonons) of solid layers and of processes which contribute to the dissipation of energy initially in the layer, such as vibrational damping and sliding friction.%%%

该补助金支持对固体表面原子和分子物理吸附层动力学的理论研究。 我们的目标是实现一个定量的理解的原子和分子与表面的相互作用的例子中，吸附物和基板被弱改性的相互作用。 这项工作是基于分析的理论和计算的结合，可以使用工作站进行。 本课程的主题包括分析固体层的简正模（声子）和分析导致层中初始能量耗散的过程，如振动阻尼和滑动摩擦。
