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."

在这个由化学系实验物理化学计划和材料研究系固态化学计划资助的奖项中，基思A.马萨诸塞州理工学院的纳尔逊和他的博士后和研究生同事将致力于进一步开发激发和控制凝聚相材料中振动和电子自由度的方法。 纳尔逊教授和他的团队将使用晶格振动（光学声子）和耦合晶格振动/电磁波（声子-极化子）运动的光学激发和控制来学习凝聚相顺序，动力学和结构的细节，以及生成定制的太赫兹（THz）频率场用于太赫兹光谱和相干控制。 纳尔逊教授和他的小组开发的方法应该成为其他有兴趣对液体和固体性质有更坚实理解的科学家的有用工具。除了支持研究的更广泛的科学和技术影响外，纳尔逊教授还通过他的“拉姆达项目”继续向高中生介绍在专用实验室进行尖端研究的兴奋。"
