Dr. 埃里克•威尔斯’ research work is centered around understanding and controlling molecular dynamics in strong laser fields.
Ultrashort laser pulses have properties that suggest they might be used to directly influence chemical reactions: The force exerted by the laser field can be comparable to the electric force that holds a molecule together, 在分子剧烈移动之前,脉冲可以被打开或关闭. 因此, precise application of a customized laser pulse to an individual molecule might enable the modification of the molecule in a targeted, 所期望的方式. 奥古斯塔的原子,分子 & optical (AMO) physics group developed a method for coupling three-dimensional ion-imaging of molecular fragments to a feedback loop that uses an adaptive learning algorithm to design laser pulses that can control specific molecular processes, 比如氢迁移和键重排.
奥古斯塔学生使用激光设备进行这项工作 J.R. 麦克唐纳实验室 at 堪萨斯州立大学 作为两个机构长期合作的一部分.
Thirty-two undergraduate students have co-authored 22 different articles as part of the work of the Augustana AMO. 这项研究得到了美国国家科学基金会的支持. 威尔斯在堪萨斯州立大学的休假得到了美国政府的支持.S. 能源部.
