Condensed Matter Coherent Spectroscopy and Control

在该奖项中，麻省理工学院的Keith A. Nelson教授和他的博士后和研究生同事将进一步开发用于激发和控制凝聚相材料的振动和电子自由度的方法，该奖项由化学部门的实验物理化学项目和材料研究部门的固体化学项目资助。Nelson教授和他的团队将利用光学激发和控制晶格振动（光学声子）和耦合晶格振动/电磁波（声子-极化电子）运动来了解凝聚态相顺序、动力学和结构的细节，以及生成定制的太赫兹（THz）频率场，用于太赫兹光谱学和相干控制。纳尔逊教授和他的团队开发的方法应该成为其他有兴趣深入了解液体和固体性质的科学家的有用工具。除了所支持的研究所带来的更广泛的科学和技术影响外，Nelson教授还通过他的“Lambda项目”，继续向高中生介绍在专门实验室进行尖端研究的兴奋之情。

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."
