项目摘要

Professor Herschel Rabitz of Princeton University is supported by an award from the Chemical Theory, Models, and Computational Methods program in the Division of Chemistry. The Chemical Structure, Dynamics and Mechanisms - A program co-funds the proposal. Rabitz seeks to understand the fundamental principles of using tailored laser fields to control phenomena at the molecular scale. Starting in the latter half of the 20th Century and accelerating to the present time, there is an increasing interest in using modern laser technology to directly manipulate the motion of atoms and molecules. Many experiments have demonstrated the feasibility of this concept. Rabitz's research seeks a fundamental understanding for why such experiments are successful. This understanding helps to provide a roadmap for performing new classes of laser experiments in the future. This roadmap includes the goal of achieving new laser-driven atomic and molecular scale transformations which are not achievable by any other means. Furthermore, Rabitz's research findings are expected to be applicable to many domains of science where controlled manipulation is required to achieve the desired outcome, even without the aid of lasers, including in the chemical and biological sciences. The control of quantum phenomena entails interceding in the normal evolution of atomic and molecular dynamical events generally through the introduction of external fields. Quite surprisingly, finding optimal fields for this purpose is proving to be far easier than anticipated, both in simulations and in the laboratory. Professor Herschel Rabitz undertakes fundamental research to understand the origins of this behavior. To address this matter at the most basic level, Rabitz explores the structure of the control landscape, which is the physical observable as a function of the control variables. The most fundamental circumstance will receive special attention, which the landscape associated with one quantum system controlling another. Rabitz will employ a family of theoretical and computational tools to analyze the landscape's topology, aiming to identify the basic rules for controlling quantum phenomena. Part of his effort includes the development of special techniques to reveal the mechanisms by which control is achieved. The outcome of Rabitz's research is expected to be a deeper understanding of controlled quantum phenomena along with specific guidance towards promising future experimental directions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

普林斯顿大学的 Herschel Rabitz 教授获得了化学系化学理论、模型和计算方法项目的奖项。化学结构、动力学和机制 - 一个项目共同资助该提案。拉比茨试图了解使用定制激光场控制分子尺度现象的基本原理。从 20 世纪下半叶开始并加速到现在，人们对使用现代激光技术直接操纵原子和分子的运动越来越感兴趣。许多实验证明了这个概念的可行性。拉比茨的研究旨在从根本上理解此类实验为何成功。这种理解有助于为未来进行新型激光实验提供路线图。该路线图包括实现新的激光驱动的原子和分子尺度转变的目标，这是任何其他方式都无法实现的。此外，拉比茨的研究成果预计将适用于许多科学领域，即使没有激光的帮助，也需要受控操作才能达到预期的结果，包括化学和生物科学。量子现象的控制通常需要通过引入外部场来干预原子和分子动力学事件的正常演化。令人惊讶的是，事实证明，无论是在模拟还是在实验室中，为此目的找到最佳场都比预期容易得多。赫歇尔·拉比茨教授进行了基础研究，以了解这种行为的起源。为了从最基本的层面解决这个问题，拉比茨探索了控制景观的结构，即作为控制变量函数的物理可观察量。最基本的情况将受到特别关注，即与一个量子系统控制另一个量子系统相关的景观。拉比茨将采用一系列理论和计算工具来分析景观的拓扑结构，旨在确定控制量子现象的基本规则。他的部分努力包括开发特殊技术来揭示实现控制的机制。 Rabitz 的研究成果预计将是对受控量子现象的更深入理解，以及对未来有希望的实验方向的具体指导。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
