Tamar Seideman of Northwestern University is supported by the Theoretical and Computational Chemistry Program and the Office of International Science and Engineering for research and education in collaboration with Leticia Gonzalez of the Free University of Berlin. These investigators will carry out a combination of advanced electronic structure calculations with quantum dynamics simulations and a recently developed theory of optimal control in dissipative environments, to explore the possibility of using coherent control tools to gain insights into the structure and dynamics of complex molecular systems. The complex systems include large biological molecules and molecules coupled to a dissipative environment. A second, related, goal is to explore the controllability by coherent light of complex systems subject to dissipation. A third goal is to develop a realistic model of the light-controlled dynamics of a number of specific systems of current experimental and either biological or technological interest. These systems include (1) phytochrome photoreceptor chromophore, found in green plants and in chemotropic bacteria, a system of currently experimental interest, and (2) overcrowded alkenes, which exhibit sterically-induced chirality. A long-term objective will be to utilize the methods and specific system details to be developed to numerically design functional molecular devices based on bio-mimicking. The synergistic nature of the international research collaboration requires close interaction of partner expertise in the different theoretical components. The participating students will be trained in complementary fields of electronic structure, reaction dynamics, and light-matter interaction, within the enriching cultural and scientific opportunities provided by the partner country. Insights will be gained into systems of general chemical interest, as well as potential biochemical and bio-mimicking relevance.

西北大学的塔玛·塞德曼（Tamar Seideman）得到了理论和计算化学计划以及与柏林自由大学的莱蒂西亚·冈萨雷斯（Leticia Gonzalez）合作的国际科学与工程学办公室。 这些研究者将结合高级电子结构计算与量子动力学模拟以及最近在耗散环境中开发的最佳控制理论，以探索使用相干控制工具的可能性，以了解对复杂分子系统的结构和动力学的见解。 复杂的系统包括大型生物分子和耦合到耗散环境的分子。 第二个相关的目标是探索通过耗散的复杂系统的相干光的可控性。 第三个目标是开发许多当前实验和生物学或技术兴趣的特定系统的光控制动力学的现实模型。 这些系统包括（1）在绿色植物和趋化细菌中发现的植物色素光感受器的发色团，这是一种当前实验性兴趣的系统，以及（2）表现出静脉诱发的chirality的烷烃。 一个长期目标将是利用基于生物模拟的数值设计功能分子设备的方法和特定系统详细信息。 国际研究合作的协同性质需要在不同理论组成部分中进行伴侣专业知识的密切相互作用。参与的学生将在合作伙伴国家提供的丰富文化和科学机会中接受电子结构，反应动态和轻度互动的互补领域的培训。洞察力将获得一般化学兴趣的系统，以及潜在的生化和模仿性相关性。
