Professor Jeffrey A. Cina, of the University of Oregon Eugene, is supported to perform research on the theory of wavepacket interferometry and relaxation dynamics. Theoretical support for the emerging field of ultrafast spectroscopy is required to aid in reconstructing molecular motion that may be inferred from measurement. A feature of this work is that the information-rich time-dependent molecular wavefunction, rather than probability density, is ultimately determined. Applications of the method are aimed at understanding quantum-state entanglement which is currently an issue of importance to quantum computing, electronic energy transfer which is a key step in photosynthesis, and chemical dynamics in solid materials and condensed-phase environments. The ability to spectrographically determine processes in and properties of large molecules has been limited until recently. The methods developed here allow one to significantly enhance capabilities for watching molecular motions and are particularly well suited to the size regime relevant to biological processes and quantum dots. Understanding gleaned from such work may impact the development and control of biologically inspired molecular materials for use in catalysis, energy storage and quantum information technologies.

Jeffrey A.支持俄勒冈州大学尤金的Cina进行波包干涉和弛豫动力学理论的研究。 新兴领域的超快光谱学的理论支持，需要帮助重建分子运动，可以推断从测量。 这项工作的一个特点是，信息丰富的时间依赖的分子波函数，而不是概率密度，最终确定。 该方法的应用旨在理解量子态纠缠，这是目前量子计算的重要问题，电子能量转移是光合作用的关键步骤，以及固体材料和凝聚相环境中的化学动力学。直到最近，用光谱法确定大分子的过程和性质的能力一直是有限的。这里开发的方法允许一个显着提高观察分子运动的能力，特别适合于与生物过程和量子点相关的大小制度。 从这些工作中获得的理解可能会影响生物启发分子材料的开发和控制，用于催化，能量存储和量子信息技术。
