In this award, funded by the Experimental Physical Chemistry Program of the Chemistry Division and the Solid State Chemistry Program of the Division of Materials Research, Prof. Keith A. Nelson of the Massachusetts Institute of Technology and his postdoctoral and graduate student colleagues will work to further develop methods for exciting and controlling the vibrational and electronic degrees of freedom in condensed phase materials. Prof. Nelson and his group will use optical excitation and control of lattice vibrations (optic phonons) and coupled lattice vibrational/electromagnetic waves (phonon-polaritrons) motions to learn details about condensed phase order, dynamics and structure, as well as to generate tailored terahertz (THz) frequency fields to be used in THz spectroscopy and coherent control. The methods that Prof. Nelson and his group develop should become useful tools for other scientists interested in developing a firmer understanding of the properties of liquids and solids. Besides the broader scientific and technological impacts of the research being supported, Prof. Nelson continues to introduce high school students to the excitement of cutting edge research in a dedicated laboratory, through his "Lambda Project."

在该奖项中，由化学部实验物理化学计划和材料研究部的固态化学计划资助，马萨诸塞州理工学院的基思·A·尼尔森教授及其博士后和他的博士后和研究生同事将致力于进一步开发了令人兴奋和控制冷凝相材料中振动和电子自由度的方法。 纳尔逊教授及其小组将使用光激发和控制晶格振动（光学声子）和耦合的晶格振动/电磁波（Phonon-Polaritrons）运动的动作来学习有关凝固相位顺序，动力学和结构的详细信息，以及生成量身定制的。 Terahertz（THZ）用于THZ光谱和相干控制的频场。 纳尔逊教授及其小组发展的方法应该成为有益于对液体和固体特性更牢固理解的其他科学家的有用工具。除了支持该研究的更广泛的科学和技术影响外，纳尔逊教授还通过其“ Lambda项目”向高中生介绍了专门的实验室中尖端研究的兴奋。
